+ *
+ * This file should be included as
+ *        #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit

+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point

+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.

+/// ## About
+/// This is a minimal state immediate mode graphical user interface toolkit
+/// written in ANSI C and licensed under public domain. It was designed as a simple
+/// embeddable user interface for application and does not have any dependencies,
+/// a default renderbackend or OS window and input handling but instead provides a very modular
+/// library approach by using simple input state for input and draw
+/// commands describing primitive shapes as output. So instead of providing a
+/// layered library that tries to abstract over a number of platform and
+/// render backends it only focuses on the actual UI.
+///
+/// ## Highlights
+/// - Graphical user interface toolkit
+/// - Single header library
+/// - Written in C89 (a.k.a. ANSI C or ISO C90)
+/// - Small codebase (~18kLOC)
+/// - Focus on portability, efficiency and simplicity

+/// ## Usage
+/// This library is self contained in one single header file and can be used either
+/// in header only mode or in implementation mode. The header only mode is used
+/// by default when included and allows including this header in other headers
+/// and does not contain the actual implementation. <br /><br />
+///
+/// The implementation mode requires to define  the preprocessor macro
+/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C
+///     #define NK_IMPLEMENTATION
+///     #include "nuklear.h"
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES"
+/// below in header and implementation mode if you want to use additional functionality
+/// or need more control over the library.
+///
+/// !!! WARNING
+///     Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions.
+///
+/// ### Flags
+/// Flag                            | Description
+/// --------------------------------|------------------------------------------
+/// NK_PRIVATE                      | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation
+/// NK_INCLUDE_FIXED_TYPES          | If defined it will include header `<stdint.h>` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself.
+/// NK_INCLUDE_DEFAULT_ALLOCATOR    | If defined it will include header `<stdlib.h>` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management.
+/// NK_INCLUDE_STANDARD_IO          | If defined it will include header `<stdio.h>` and provide additional functions depending on file loading.
+/// NK_INCLUDE_STANDARD_VARARGS     | If defined it will include header <stdio.h> and provide additional functions depending on file loading.
+/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,...
+/// NK_INCLUDE_FONT_BAKING          | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it.
+/// NK_INCLUDE_DEFAULT_FONT         | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
+/// NK_INCLUDE_COMMAND_USERDATA     | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures.
+/// NK_BUTTON_TRIGGER_ON_RELEASE    | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released.
+/// NK_ZERO_COMMAND_MEMORY          | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame.
+///
+/// !!! WARNING
+///     The following flags will pull in the standard C library:
+///     - NK_INCLUDE_DEFAULT_ALLOCATOR
+///     - NK_INCLUDE_STANDARD_IO
+///     - NK_INCLUDE_STANDARD_VARARGS
+///
+/// !!! WARNING
+///     The following flags if defined need to be defined for both header and implementation:
+///     - NK_INCLUDE_FIXED_TYPES
+///     - NK_INCLUDE_DEFAULT_ALLOCATOR
+///     - NK_INCLUDE_STANDARD_VARARGS
+///     - NK_INCLUDE_VERTEX_BUFFER_OUTPUT
+///     - NK_INCLUDE_FONT_BAKING
+///     - NK_INCLUDE_DEFAULT_FONT
+///     - NK_INCLUDE_STANDARD_VARARGS
+///     - NK_INCLUDE_COMMAND_USERDATA
+///
+/// ### Constants
+/// Define                          | Description
+/// --------------------------------|---------------------------------------
+/// NK_BUFFER_DEFAULT_INITIAL_SIZE  | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it.
+/// NK_MAX_NUMBER_BUFFER            | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient.
+/// NK_INPUT_MAX                    | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient.
+///
+/// !!! WARNING
+///     The following constants if defined need to be defined for both header and implementation:
+///     - NK_MAX_NUMBER_BUFFER
+///     - NK_BUFFER_DEFAULT_INITIAL_SIZE
+///     - NK_INPUT_MAX
+///
+/// ### Dependencies
+/// Function    | Description
+/// ------------|---------------------------------------------------------------
+/// NK_ASSERT   | If you don't define this, nuklear will use <assert.h> with assert().
+/// NK_MEMSET   | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version.
+/// NK_MEMCPY   | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version.
+/// NK_SQRT     | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version.
+/// NK_SIN      | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_COS      | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation.
+/// NK_STRTOD   | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_DTOA     | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!).
+/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe.
+///
+/// !!! WARNING
+///     The following dependencies will pull in the standard C library if not redefined:
+///     - NK_ASSERT
+///
+/// !!! WARNING
+///     The following dependencies if defined need to be defined for both header and implementation:
+///     - NK_ASSERT
+///
+/// !!! WARNING
+///     The following dependencies if defined need to be defined only for the implementation part:
+///     - NK_MEMSET
+///     - NK_MEMCPY

+///     - NK_SIN
+///     - NK_COS

+/// The input API is responsible for holding the current input state composed of

+/// It is worth noting that no direct OS or window handling is done in nuklear.
+/// Instead all input state has to be provided by platform specific code. This on one hand
+/// expects more work from the user and complicates usage but on the other hand
+/// provides simple abstraction over a big number of platforms, libraries and other
+/// already provided functionality.

+/// Both event- or state-based input handling are supported by this API
+/// and should work without problems. Finally after all input state has been
+/// mirrored `nk_input_end` needs to be called to finish input process.

+ *
+ * =============================================================================*/
+/*/// ### Drawing
+/// This library was designed to be render backend agnostic so it does
+/// not draw anything to screen directly. Instead all drawn shapes, widgets
+/// are made of, are buffered into memory and make up a command queue.
+/// Each frame therefore fills the command buffer with draw commands
+/// that then need to be executed by the user and his own render backend.
+/// After that the command buffer needs to be cleared and a new frame can be
+/// started. It is probably important to note that the command buffer is the main
+/// drawing API and the optional vertex buffer API only takes this format and
+/// converts it into a hardware accessible format.
+///
+/// #### Usage
+/// To draw all draw commands accumulated over a frame you need your own render
+/// backend able to draw a number of 2D primitives. This includes at least
+/// filled and stroked rectangles, circles, text, lines, triangles and scissors.
+/// As soon as this criterion is met you can iterate over each draw command
+/// and execute each draw command in a interpreter like fashion:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// const struct nk_command *cmd = 0;
+/// nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)
+///         break;
+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case //...:
+///         //[...]
+///     }
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In program flow context draw commands need to be executed after input has been
+/// gathered and the complete UI with windows and their contained widgets have
+/// been executed and before calling `nk_clear` which frees all previously
+/// allocated draw commands.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             [...]
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // [...]
+///     //
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)

+///     case NK_COMMAND_RECT
+///         your_draw_rect_function(...)
+///         break;
+///     case ...:
+///         // [...]
+///     }

+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// You probably noticed that you have to draw all of the UI each frame which is
+/// quite wasteful. While the actual UI updating loop is quite fast rendering
+/// without actually needing it is not. So there are multiple things you could do.
+///
+/// First is only update on input. This of course is only an option if your
+/// application only depends on the UI and does not require any outside calculations.
+/// If you actually only update on input make sure to update the UI two times each
+/// frame and call `nk_clear` directly after the first pass and only draw in
+/// the second pass. In addition it is recommended to also add additional timers
+/// to make sure the UI is not drawn more than a fixed number of frames per second.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // [...wait for input ]
+///     // [...do two UI passes ...]
+///     do_ui(...)
+///     nk_clear(&ctx);
+///     do_ui(...)
+///     //
+///     // draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     switch (cmd->type) {
+///     case NK_COMMAND_LINE:
+///         your_draw_line_function(...)

+///         //[...]
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// The second probably more applicable trick is to only draw if anything changed.
+/// It is not really useful for applications with continuous draw loop but
+/// quite useful for desktop applications. To actually get nuklear to only
+/// draw on changes you first have to define `NK_ZERO_COMMAND_MEMORY` and
+/// allocate a memory buffer that will store each unique drawing output.
+/// After each frame you compare the draw command memory inside the library
+/// with your allocated buffer by memcmp. If memcmp detects differences
+/// you have to copy the command buffer into the allocated buffer
+/// and then draw like usual (this example uses fixed memory but you could
+/// use dynamically allocated memory).
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// //[... other defines ...]
+/// #define NK_ZERO_COMMAND_MEMORY
+/// #include "nuklear.h"

+/// struct nk_context ctx;
+/// void *last = calloc(1,64*1024);

+/// //
+/// // loop
+/// while (1) {
+///     // [...input...]
+///     // [...ui...]
+///     void *cmds = nk_buffer_memory(&ctx.memory);
+///     if (memcmp(cmds, last, ctx.memory.allocated)) {
+///         memcpy(last,cmds,ctx.memory.allocated);
+///         const struct nk_command *cmd = 0;
+///         nk_foreach(cmd, &ctx) {
+///             switch (cmd->type) {
+///             case NK_COMMAND_LINE:
+///                 your_draw_line_function(...)
+///                 break;
+///             case NK_COMMAND_RECT
+///                 your_draw_rect_function(...)
+///                 break;
+///             case ...:

+///         }
+///     }
+///     nk_clear(&ctx);
+/// }
+/// nk_free(&ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// Finally while using draw commands makes sense for higher abstracted platforms like
+/// X11 and Win32 or drawing libraries it is often desirable to use graphics
+/// hardware directly. Therefore it is possible to just define
+/// `NK_INCLUDE_VERTEX_BUFFER_OUTPUT` which includes optional vertex output.
+/// To access the vertex output you first have to convert all draw commands into

+ *                                  WINDOW
+ *
+ * =============================================================================
+/// ### Window
+/// Windows are the main persistent state used inside nuklear and are life time
+/// controlled by simply "retouching" (i.e. calling) each window each frame.
+/// All widgets inside nuklear can only be added inside the function pair `nk_begin_xxx`
+/// and `nk_end`. Calling any widgets outside these two functions will result in an
+/// assert in debug or no state change in release mode.<br /><br />
+///
+/// Each window holds frame persistent state like position, size, flags, state tables,
+/// and some garbage collected internal persistent widget state. Each window
+/// is linked into a window stack list which determines the drawing and overlapping
+/// order. The topmost window thereby is the currently active window.<br /><br />
+///
+/// To change window position inside the stack occurs either automatically by
+/// user input by being clicked on or programmatically by calling `nk_window_focus`.
+/// Windows by default are visible unless explicitly being defined with flag
+/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag
+/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling
+/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.<br /><br />
+///
+/// #### Usage
+/// To create and keep a window you have to call one of the two `nk_begin_xxx`
+/// functions to start window declarations and `nk_end` at the end. Furthermore it
+/// is recommended to check the return value of `nk_begin_xxx` and only process
+/// widgets inside the window if the value is not 0. Either way you have to call
+/// `nk_end` at the end of window declarations. Furthermore, do not attempt to
+/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not
+/// in a segmentation fault.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_begin_xxx(...) {
+///     // [... widgets ...]
+/// }
+/// nk_end(ctx);
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept window and widget declarations need to occur after input
+/// handling and before drawing to screen. Not doing so can result in higher
+/// latency or at worst invalid behavior. Furthermore make sure that `nk_clear`
+/// is called at the end of the frame. While nuklear's default platform backends
+/// already call `nk_clear` for you if you write your own backend not calling
+/// `nk_clear` can cause asserts or even worse undefined behavior.
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             nk_input_xxx(...);
+///         }
+///     }
+///     nk_input_end(&ctx);
+///
+///     if (nk_begin_xxx(...) {
+///         //[...]
+///     }
+///     nk_end(ctx);
+///
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {
+///     case NK_COMMAND_LINE:

+ *
+ * =============================================================================
+/// ### Layouting
+/// Layouting in general describes placing widget inside a window with position and size.
+/// While in this particular implementation there are five different APIs for layouting
+/// each with different trade offs between control and ease of use. <br /><br />
+///
+/// All layouting methods in this library are based around the concept of a row.
+/// A row has a height the window content grows by and a number of columns and each
+/// layouting method specifies how each widget is placed inside the row.
+/// After a row has been allocated by calling a layouting functions and then
+/// filled with widgets will advance an internal pointer over the allocated row. <br /><br />
+///
+/// To actually define a layout you just call the appropriate layouting function
+/// and each subsequent widget call will place the widget as specified. Important
+/// here is that if you define more widgets then columns defined inside the layout
+/// functions it will allocate the next row without you having to make another layouting <br /><br />
+/// call.
+///
+/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API
+/// is that you have to define the row height for each. However the row height
+/// often depends on the height of the font. <br /><br />
+///
+/// To fix that internally nuklear uses a minimum row height that is set to the
+/// height plus padding of currently active font and overwrites the row height
+/// value if zero. <br /><br />
+///
+/// If you manually want to change the minimum row height then
+/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to
+/// reset it back to be derived from font height. <br /><br />
+///
+/// Also if you change the font in nuklear it will automatically change the minimum
+/// row height for you and. This means if you change the font but still want
+/// a minimum row height smaller than the font you have to repush your value. <br /><br />
+///
+/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx`
+/// layouting method in combination with a cassowary constraint solver (there are
+/// some versions on github with permissive license model) to take over all control over widget
+/// layouting yourself. However for quick and dirty layouting using all the other layouting
+/// functions should be fine.
+///
+/// #### Usage
+/// 1.  __nk_layout_row_dynamic__<br /><br />
+///     The easiest layouting function is `nk_layout_row_dynamic`. It provides each
+///     widgets with same horizontal space inside the row and dynamically grows
+///     if the owning window grows in width. So the number of columns dictates
+///     the size of each widget dynamically by formula:
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     widget_width = (window_width - padding - spacing) * (1/colum_count)
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+///     Just like all other layouting APIs if you define more widget than columns this
+///     library will allocate a new row and keep all layouting parameters previously
+///     defined.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets
+///         nk_layout_row_dynamic(&ctx, 30, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_dynamic(&ctx, 0, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 2.  __nk_layout_row_static__<br /><br />
+///     Another easy layouting function is `nk_layout_row_static`. It provides each
+///     widget with same horizontal pixel width inside the row and does not grow
+///     if the owning window scales smaller or bigger.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 30 composed of two widgets with width: 80
+///         nk_layout_row_static(&ctx, 30, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // second row with same parameter as defined above
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // third row uses 0 for height which will use auto layouting
+///         nk_layout_row_static(&ctx, 0, 80, 2);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 3.  __nk_layout_row_xxx__<br /><br />
+///     A little bit more advanced layouting API are functions `nk_layout_row_begin`,
+///     `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly
+///     specify each column pixel or window ratio in a row. It supports either
+///     directly setting per column pixel width or widget window ratio but not
+///     both. Furthermore it is a immediate mode API so each value is directly
+///     pushed before calling a widget. Therefore the layout is not automatically
+///     repeating like the last two layouting functions.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // first row with height: 25 composed of two widgets with width 60 and 40
+///         nk_layout_row_begin(ctx, NK_STATIC, 25, 2);
+///         nk_layout_row_push(ctx, 60);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 40);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///         //
+///         // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75
+///         nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2);
+///         nk_layout_row_push(ctx, 0.25f);
+///         nk_widget(...);
+///         nk_layout_row_push(ctx, 0.75f);
+///         nk_widget(...);
+///         nk_layout_row_end(ctx);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 4.  __nk_layout_row__<br /><br />
+///     The array counterpart to API nk_layout_row_xxx is the single nk_layout_row
+///     functions. Instead of pushing either pixel or window ratio for every widget
+///     it allows to define it by array. The trade of for less control is that
+///     `nk_layout_row` is automatically repeating. Otherwise the behavior is the
+///     same.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of two widgets with width 60 and 40
+///         const float size[] = {60,40};
+///         nk_layout_row(ctx, NK_STATIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         //
+///         // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75
+///         const float ratio[] = {0.25, 0.75};
+///         nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);
+///     }
+///     nk_end(...);
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// 5.  __nk_layout_row_template_xxx__<br /><br />
+///     The most complex and second most flexible API is a simplified flexbox version without
+///     line wrapping and weights for dynamic widgets. It is an immediate mode API but
+///     unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called
+///     before calling the templated widgets.
+///     The row template layout has three different per widget size specifier. The first
+///     one is the `nk_layout_row_template_push_static`  with fixed widget pixel width.
+///     They do not grow if the row grows and will always stay the same.
+///     The second size specifier is `nk_layout_row_template_push_variable`
+///     which defines a minimum widget size but it also can grow if more space is available
+///     not taken by other widgets.
+///     Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic`
+///     which are completely flexible and unlike variable widgets can even shrink
+///     to zero if not enough space is provided.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // two rows with height: 30 composed of three widgets
+///         nk_layout_row_template_begin(ctx, 30);
+///         nk_layout_row_template_push_dynamic(ctx);
+///         nk_layout_row_template_push_variable(ctx, 80);
+///         nk_layout_row_template_push_static(ctx, 80);
+///         nk_layout_row_template_end(ctx);
+///         //
+///         // first row
+///         nk_widget(...); // dynamic widget can go to zero if not enough space
+///         nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space
+///         nk_widget(...); // static widget with fixed 80 pixel width
+///         //
+///         // second row same layout
+///         nk_widget(...);
+///         nk_widget(...);
+///         nk_widget(...);

+///
+/// 6.  __nk_layout_space_xxx__<br /><br />
+///     Finally the most flexible API directly allows you to place widgets inside the
+///     window. The space layout API is an immediate mode API which does not support
+///     row auto repeat and directly sets position and size of a widget. Position
+///     and size hereby can be either specified as ratio of allocated space or
+///     allocated space local position and pixel size. Since this API is quite
+///     powerful there are a number of utility functions to get the available space
+///     and convert between local allocated space and screen space.
+///
+///     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+///     if (nk_begin_xxx(...) {
+///         // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered)
+///         nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX);

+ *
+ * =============================================================================
+/// ### Groups
+/// Groups are basically windows inside windows. They allow to subdivide space
+/// in a window to layout widgets as a group. Almost all more complex widget
+/// layouting requirements can be solved using groups and basic layouting
+/// fuctionality. Groups just like windows are identified by an unique name and
+/// internally keep track of scrollbar offsets by default. However additional
+/// versions are provided to directly manage the scrollbar.
+///
+/// #### Usage
+/// To create a group you have to call one of the three `nk_group_begin_xxx`
+/// functions to start group declarations and `nk_group_end` at the end. Furthermore it
+/// is required to check the return value of `nk_group_begin_xxx` and only process
+/// widgets inside the window if the value is not 0.
+/// Nesting groups is possible and even encouraged since many layouting schemes
+/// can only be achieved by nesting. Groups, unlike windows, need `nk_group_end`
+/// to be only called if the corosponding `nk_group_begin_xxx` call does not return 0:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// if (nk_group_begin_xxx(ctx, ...) {
+///     // [... widgets ...]
+///     nk_group_end(ctx);
+/// }
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+///
+/// In the grand concept groups can be called after starting a window
+/// with `nk_begin_xxx` and before calling `nk_end`:
+///
+/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c
+/// struct nk_context ctx;
+/// nk_init_xxx(&ctx, ...);
+/// while (1) {
+///     // Input
+///     Event evt;
+///     nk_input_begin(&ctx);
+///     while (GetEvent(&evt)) {
+///         if (evt.type == MOUSE_MOVE)
+///             nk_input_motion(&ctx, evt.motion.x, evt.motion.y);
+///         else if (evt.type == [...]) {
+///             nk_input_xxx(...);
+///         }
+///     }
+///     nk_input_end(&ctx);
+///     //
+///     // Window
+///     if (nk_begin_xxx(...) {
+///         // [...widgets...]
+///         nk_layout_row_dynamic(...);
+///         if (nk_group_begin_xxx(ctx, ...) {
+///             //[... widgets ...]
+///             nk_group_end(ctx);
+///         }
+///     }
+///     nk_end(ctx);
+///     //
+///     // Draw
+///     const struct nk_command *cmd = 0;
+///     nk_foreach(cmd, &ctx) {

+ * ============================================================================= 
+/// ### Tree
+/// Trees represent two different concept. First the concept of a collapsable
+/// UI section that can be either in a hidden or visibile state. They allow the UI
+/// user to selectively minimize the current set of visible UI to comprehend.
+/// The second concept are tree widgets for visual UI representation of trees.<br /><br />
+///
+/// Trees thereby can be nested for tree representations and multiple nested
+/// collapsable UI sections. All trees are started by calling of the
+/// `nk_tree_xxx_push_tree` functions and ended by calling one of the
+/// `nk_tree_xxx_pop_xxx()` functions. Each starting functions takes a title label
+/// and optionally an image to be displayed and the initial collapse state from
+/// the nk_collapse_states section.<br /><br />
+///
+/// The runtime state of the tree is either stored outside the library by the caller
+/// or inside which requires a unique ID. The unique ID can either be generated
+/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`,
+/// by `__FILE__` and a user provided ID generated for example by loop index with
+/// function `nk_tree_push_id` or completely provided from outside by user with
+/// function `nk_tree_push_hashed`.
+///
+/// #### Usage
+/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx`
+/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the
+/// end.
+/// Each starting function will either return `false(0)` if the tree is collapsed
+/// or hidden and therefore does not need to be filled with content or `true(1)`
+/// if visible and required to be filled.
+///
+/// !!! Note
+///     The tree header does not require and layouting function and instead
+///     calculates a auto height based on the currently used font size
+///
+/// The tree ending functions only need to be called if the tree content is
+/// actually visible. So make sure the tree push function is guarded by `if`
+/// and the pop call is only taken if the tree is visible.

+/// ### Properties
+/// Properties are the main value modification widgets in Nuklear. Changing a value
+/// can be achieved by dragging, adding/removing incremental steps on button click
+/// or by directly typing a number.
+///
+/// #### Usage
+/// Each property requires a unique name for identifaction that is also used for
+/// displaying a label. If you want to use the same name multiple times make sure
+/// add a '#' before your name. The '#' will not be shown but will generate a
+/// unique ID. Each propery also takes in a minimum and maximum value. If you want
+/// to make use of the complete number range of a type just use the provided
+/// type limits from `limits.h`. For example `INT_MIN` and `INT_MAX` for
+/// `nk_property_int` and `nk_propertyi`. In additional each property takes in
+/// a increment value that will be added or subtracted if either the increment
+/// decrement button is clicked. Finally there is a value for increment per pixel
+/// dragged that is added or subtracted from the value.
+///

+/*  Font handling in this library was designed to be quite customizable and lets
+    you decide what you want to use and what you want to provide. There are three
+    different ways to use the font atlas. The first two will use your font
+    handling scheme and only requires essential data to run nuklear. The next
+    slightly more advanced features is font handling with vertex buffer output.
+    Finally the most complex API wise is using nuklear's font baking API.
+
+    1.) Using your own implementation without vertex buffer output
+    --------------------------------------------------------------
+    So first up the easiest way to do font handling is by just providing a
+    `nk_user_font` struct which only requires the height in pixel of the used
+    font and a callback to calculate the width of a string. This way of handling
+    fonts is best fitted for using the normal draw shape command API where you
+    do all the text drawing yourself and the library does not require any kind
+    of deeper knowledge about which font handling mechanism you use.
+    IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist
+    over the complete life time! I know this sucks but it is currently the only
+    way to switch between fonts.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    2.) Using your own implementation with vertex buffer output
+    --------------------------------------------------------------
+    While the first approach works fine if you don't want to use the optional
+    vertex buffer output it is not enough if you do. To get font handling working
+    for these cases you have to provide two additional parameters inside the
+    `nk_user_font`. First a texture atlas handle used to draw text as subimages
+    of a bigger font atlas texture and a callback to query a character's glyph
+    information (offset, size, ...). So it is still possible to provide your own
+    font and use the vertex buffer output.
+
+        float your_text_width_calculation(nk_handle handle, float height, const char *text, int len)
+        {
+            your_font_type *type = handle.ptr;
+            float text_width = ...;
+            return text_width;
+        }
+        void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint)
+        {
+            your_font_type *type = handle.ptr;
+            glyph.width = ...;
+            glyph.height = ...;
+            glyph.xadvance = ...;
+            glyph.uv[0].x = ...;
+            glyph.uv[0].y = ...;
+            glyph.uv[1].x = ...;
+            glyph.uv[1].y = ...;
+            glyph.offset.x = ...;
+            glyph.offset.y = ...;
+        }
+
+        struct nk_user_font font;
+        font.userdata.ptr = &your_font_class_or_struct;
+        font.height = your_font_height;
+        font.width = your_text_width_calculation;
+        font.query = query_your_font_glyph;
+        font.texture.id = your_font_texture;
+
+        struct nk_context ctx;
+        nk_init_default(&ctx, &font);
+
+    3.) Nuklear font baker
+    ------------------------------------
+    The final approach if you do not have a font handling functionality or don't
+    want to use it in this library is by using the optional font baker.
+    The font baker APIs can be used to create a font plus font atlas texture
+    and can be used with or without the vertex buffer output.
+
+    It still uses the `nk_user_font` struct and the two different approaches
+    previously stated still work. The font baker is not located inside
+    `nk_context` like all other systems since it can be understood as more of
+    an extension to nuklear and does not really depend on any `nk_context` state.
+
+    Font baker need to be initialized first by one of the nk_font_atlas_init_xxx
+    functions. If you don't care about memory just call the default version
+    `nk_font_atlas_init_default` which will allocate all memory from the standard library.
+    If you want to control memory allocation but you don't care if the allocated
+    memory is temporary and therefore can be freed directly after the baking process
+    is over or permanent you can call `nk_font_atlas_init`.
+
+    After successfully initializing the font baker you can add Truetype(.ttf) fonts from
+    different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`.
+    functions. Adding font will permanently store each font, font config and ttf memory block(!)
+    inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
+    the font baker by for example adding additional fonts you can call
+    `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end).
+
+    As soon as you added all fonts you wanted you can now start the baking process
+    for every selected glyph to image by calling `nk_font_atlas_bake`.
+    The baking process returns image memory, width and height which can be used to
+    either create your own image object or upload it to any graphics library.
+    No matter which case you finally have to call `nk_font_atlas_end` which
+    will free all temporary memory including the font atlas image so make sure
+    you created our texture beforehand. `nk_font_atlas_end` requires a handle
+    to your font texture or object and optionally fills a `struct nk_draw_null_texture`
+    which can be used for the optional vertex output. If you don't want it just
+    set the argument to `NULL`.
+
+    At this point you are done and if you don't want to reuse the font atlas you
+    can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration
+    memory. Finally if you don't use the font atlas and any of it's fonts anymore
+    you need to call `nk_font_atlas_clear` to free all memory still being used.

+
+    The font baker API is probably the most complex API inside this library and
+    I would suggest reading some of my examples `example/` to get a grip on how
+    to use the font atlas. There are a number of details I left out. For example
+    how to merge fonts, configure a font with `nk_font_config` to use other languages,
+    use another texture coordinate format and a lot more:
+
+        struct nk_font_config cfg = nk_font_config(font_pixel_height);
+        cfg.merge_mode = nk_false or nk_true;
+        cfg.range = nk_font_korean_glyph_ranges();
+        cfg.coord_type = NK_COORD_PIXEL;
+        nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, &cfg);

+ *                          MEMORY BUFFER
+ *
+ * ===============================================================*/
+/*  A basic (double)-buffer with linear allocation and resetting as only
+    freeing policy. The buffer's main purpose is to control all memory management
+    inside the GUI toolkit and still leave memory control as much as possible in
+    the hand of the user while also making sure the library is easy to use if
+    not as much control is needed.
+    In general all memory inside this library can be provided from the user in
+    three different ways.
+
+    The first way and the one providing most control is by just passing a fixed
+    size memory block. In this case all control lies in the hand of the user
+    since he can exactly control where the memory comes from and how much memory
+    the library should consume. Of course using the fixed size API removes the
+    ability to automatically resize a buffer if not enough memory is provided so
+    you have to take over the resizing. While being a fixed sized buffer sounds
+    quite limiting, it is very effective in this library since the actual memory
+    consumption is quite stable and has a fixed upper bound for a lot of cases.
+
+    If you don't want to think about how much memory the library should allocate
+    at all time or have a very dynamic UI with unpredictable memory consumption
+    habits but still want control over memory allocation you can use the dynamic
+    allocator based API. The allocator consists of two callbacks for allocating
+    and freeing memory and optional userdata so you can plugin your own allocator.
+
+    The final and easiest way can be used by defining
+    NK_INCLUDE_DEFAULT_ALLOCATOR which uses the standard library memory
+    allocation functions malloc and free and takes over complete control over
+    memory in this library.

+ * as well as functionality controlled by flags.
+ *
+ * This library generally allows three different levels of memory control:
+ * First of is the most basic way of just providing a simple char array with

+ *
+ * For UIs that require undo/redo the second way was created. It is based on

+ * This is mainly useful if you want something more like a text editor but don't want
+ * to have a dynamically growing buffer.
+ *
+ * The final way is using a dynamically growing nk_text_edit struct, which
+ * has both a default version if you don't care where memory comes from and an
+ * allocator version if you do. While the text editor is quite powerful for its

+ *
+ * ===============================================================*/
+/*  This library was designed to be render backend agnostic so it does
+    not draw anything to screen. Instead all drawn shapes, widgets
+    are made of, are buffered into memory and make up a command queue.
+    Each frame therefore fills the command buffer with draw commands
+    that then need to be executed by the user and his own render backend.
+    After that the command buffer needs to be cleared and a new frame can be
+    started. It is probably important to note that the command buffer is the main
+    drawing API and the optional vertex buffer API only takes this format and
+    converts it into a hardware accessible format.
+
+    To use the command queue to draw your own widgets you can access the
+    command buffer of each window by calling `nk_window_get_canvas` after
+    previously having called `nk_begin`:
+
+        void draw_red_rectangle_widget(struct nk_context *ctx)
+        {
+            struct nk_command_buffer *canvas;
+            struct nk_input *input = &ctx->input;
+            canvas = nk_window_get_canvas(ctx);
+
+            struct nk_rect space;
+            enum nk_widget_layout_states state;
+            state = nk_widget(&space, ctx);
+            if (!state) return;
+
+            if (state != NK_WIDGET_ROM)
+                update_your_widget_by_user_input(...);
+            nk_fill_rect(canvas, space, 0, nk_rgb(255,0,0));
+        }
+
+        if (nk_begin(...)) {
+            nk_layout_row_dynamic(ctx, 25, 1);
+            draw_red_rectangle_widget(ctx);
+        }
+        nk_end(..)
+
+    Important to know if you want to create your own widgets is the `nk_widget`
+    call. It allocates space on the panel reserved for this widget to be used,
+    but also returns the state of the widget space. If your widget is not seen and does
+    not have to be updated it is '0' and you can just return. If it only has
+    to be drawn the state will be `NK_WIDGET_ROM` otherwise you can do both
+    update and draw your widget. The reason for separating is to only draw and
+    update what is actually necessary which is crucial for performance.

+/*  Since nuklear is supposed to work on all systems providing floating point
+    math without any dependencies I also had to implement my own math functions
+    for sqrt, sin and cos. Since the actual highly accurate implementations for
+    the standard library functions are quite complex and I do not need high
+    precision for my use cases I use approximations.
+
+    Sqrt
+    ----
+    For square root nuklear uses the famous fast inverse square root:
+    https://en.wikipedia.org/wiki/Fast_inverse_square_root with
+    slightly tweaked magic constant. While on today's hardware it is
+    probably not faster it is still fast and accurate enough for
+    nuklear's use cases. IMPORTANT: this requires float format IEEE 754
+
+    Sine/Cosine
+    -----------
+    All constants inside both function are generated Remez's minimax
+    approximations for value range 0...2*PI. The reason why I decided to
+    approximate exactly that range is that nuklear only needs sine and
+    cosine to generate circles which only requires that exact range.
+    In addition I used Remez instead of Taylor for additional precision:
+    www.lolengine.net/blog/2011/12/21/better-function-approximations.
+
+    The tool I used to generate constants for both sine and cosine
+    (it can actually approximate a lot more functions) can be
+    found here: www.lolengine.net/wiki/oss/lolremez

+/// [date][x.yy.zz]-[description]
+/// -[date]: date on which the change has been pushed
+/// -[x.yy.zz]: Numerical version string representation. Each version number on the right
+///             resets back to zero if version on the left is incremented.
+///    - [x]: Major version with API and library breaking changes
+///    - [yy]: Minor version with non-breaking API and library changes
+///    - [zz]: Bug fix version with no direct changes to API
+///
+/// - 2018/04/01 (4.00.1) - Fixed calling `nk_convert` multiple time per single frame
+/// - 2018/04/01 (4.00.0) - BREAKING CHANGE: nk_draw_list_clear no longer tries to
+///                         clear provided buffers. So make sure to either free
+///                         or clear each passed buffer after calling nk_convert.
+/// - 2018/02/23 (3.00.6) - Fixed slider dragging behavior
+/// - 2018/01/31 (3.00.5) - Fixed overcalculation of cursor data in font baking process
+/// - 2018/01/31 (3.00.4) - Removed name collision with stb_truetype
+/// - 2018/01/28 (3.00.3) - Fixed panel window border drawing bug
+/// - 2018/01/12 (3.00.2) - Added `nk_group_begin_titled` for separed group identifier and title
+/// - 2018/01/07 (3.00.1) - Started to change documentation style
+/// - 2018/01/05 (3.00.0) - BREAKING CHANGE: The previous color picker API was broken
+///                        because of conversions between float and byte color representation.
+///                        Color pickers now use floating point values to represent
+///                        HSV values. To get back the old behavior I added some additional
+///                        color conversion functions to cast between nk_color and
+///                        nk_colorf.

+///                        require the name of the window and must happen outside the window
+///                        building process (between function call nk_begin and nk_end).
+/// - 2017/09/11 (1.40.9) - Fixed window background flag if background window is declared last
+/// - 2017/08/27 (1.40.8) - Fixed `nk_item_is_any_active` for hidden windows

+///                        and filled rectangles
+/// - 2017/07/07 (1.40.4) - Fixed bug in nk_convert trying to add windows that are in
+///                        process of being destroyed.
+/// - 2017/07/07 (1.40.3) - Fixed table internal bug caused by storing table size in
+///                        window instead of directly in table.
+/// - 2017/06/30 (1.40.2) - Removed unneeded semicolon in C++ NK_ALIGNOF macro
+/// - 2017/06/30 (1.40.1) - Fixed drawing lines smaller or equal zero
+/// - 2017/06/08 (1.40.0) - Removed the breaking part of last commit. Auto layout now only
+///                        comes in effect if you pass in zero was row height argument
+/// - 2017/06/08 (1.40.0) - BREAKING CHANGE: while not directly API breaking it will change
+///                        how layouting works. From now there will be an internal minimum
+///                        row height derived from font height. If you need a row smaller than
+///                        that you can directly set it by `nk_layout_set_min_row_height` and
+///                        reset the value back by calling `nk_layout_reset_min_row_height.
+/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix
+/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a nk_layout_xxx function
+/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer
+/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped
+/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundries
+/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space
+/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size
+/// - 2017/05/06 (1.38.0) - Added platform double-click support
+/// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends

+/// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows
+/// - 2017/03/25 (1.35.1) - Fixed windows closing behavior
+/// - 2017/03/18 (1.35.0) - Added horizontal scroll requested in #377
+/// - 2017/03/18 (1.34.3) - Fixed long window header titles
+/// - 2017/03/04 (1.34.2) - Fixed text edit filtering

+/// - 2017/01/24 (1.33.0) - Added programatic way of remove edit focus
+/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows
+/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows
+/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing
+/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner
+/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both
+///                        dynamic and static widgets.
+/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit
+/// - 2016/12/31 (1.29.2)- Fixed closing window bug of minimized windows
+/// - 2016/12/03 (1.29.1)- Fixed wrapped text with no seperator and C89 error
+/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters
+/// - 2016/11/22 (1.28.6)- Fixed window minimized closing bug
+/// - 2016/11/19 (1.28.5)- Fixed abstract combo box closing behavior
+/// - 2016/11/19 (1.28.4)- Fixed tooltip flickering
+/// - 2016/11/19 (1.28.3)- Fixed memory leak caused by popup repeated closing
+/// - 2016/11/18 (1.28.2)- Fixed memory leak caused by popup panel allocation
+/// - 2016/11/10 (1.28.1)- Fixed some warnings and C++ error
+/// - 2016/11/10 (1.28.0)- Added additional `nk_button` versions which allows to directly
+///                        pass in a style struct to change buttons visual.
+/// - 2016/11/10 (1.27.0)- Added additional 'nk_tree' versions to support external state
+///                        storage. Just like last the `nk_group` commit the main
+///                        advantage is that you optionally can minimize nuklears runtime
+///                        memory consumption or handle hash collisions.
+/// - 2016/11/09 (1.26.0)- Added additional `nk_group` version to support external scrollbar
+///                        offset storage. Main advantage is that you can externalize
+///                        the memory management for the offset. It could also be helpful
+///                        if you have a hash collision in `nk_group_begin` but really
+///                        want the name. In addition I added `nk_list_view` which allows
+///                        to draw big lists inside a group without actually having to
+///                        commit the whole list to nuklear (issue #269).
+/// - 2016/10/30 (1.25.1)- Fixed clipping rectangle bug inside `nk_draw_list`
+/// - 2016/10/29 (1.25.0)- Pulled `nk_panel` memory management into nuklear and out of
+///                        the hands of the user. From now on users don't have to care
+///                        about panels unless they care about some information. If you
+///                        still need the panel just call `nk_window_get_panel`.
+/// - 2016/10/21 (1.24.0)- Changed widget border drawing to stroked rectangle from filled
+///                        rectangle for less overdraw and widget background transparency.
+/// - 2016/10/18 (1.23.0)- Added `nk_edit_focus` for manually edit widget focus control
+/// - 2016/09/29 (1.22.7)- Fixed deduction of basic type in non `<stdint.h>` compilation
+/// - 2016/09/29 (1.22.6)- Fixed edit widget UTF-8 text cursor drawing bug
+/// - 2016/09/28 (1.22.5)- Fixed edit widget UTF-8 text appending/inserting/removing
+/// - 2016/09/28 (1.22.4)- Fixed drawing bug inside edit widgets which offset all text
+///                        text in every edit widget if one of them is scrolled.
+/// - 2016/09/28 (1.22.3)- Fixed small bug in edit widgets if not active. The wrong
+///                        text length is passed. It should have been in bytes but
+///                        was passed as glyphes.
+/// - 2016/09/20 (1.22.2)- Fixed color button size calculation
+/// - 2016/09/20 (1.22.1)- Fixed some `nk_vsnprintf` behavior bugs and removed
+///                        `<stdio.h>` again from `NK_INCLUDE_STANDARD_VARARGS`.
+/// - 2016/09/18 (1.22.0)- C89 does not support vsnprintf only C99 and newer as well
+///                        as C++11 and newer. In addition to use vsnprintf you have
+///                        to include <stdio.h>. So just defining `NK_INCLUDE_STD_VAR_ARGS`
+///                        is not enough. That behavior is now fixed. By default if
+///                        both varargs as well as stdio is selected I try to use
+///                        vsnprintf if not possible I will revert to vsprintf. If
+///                        varargs but not stdio was defined I will use my own function.
+/// - 2016/09/15 (1.21.2)- Fixed panel `close` behavior for deeper panel levels
+/// - 2016/09/15 (1.21.1)- Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`
+/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo,
+///                        and contextual which prevented closing in y-direction if
+///                        popup did not reach max height.
+///                        In addition the height parameter was changed into vec2
+///                        for width and height to have more control over the popup size.
+/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection
+/// - 2016/09/13 (1.20.2)- Fixed slider behavior hopefully for the last time. This time
+///                        all calculation are correct so no more hackery.
+/// - 2016/09/13 (1.20.1)- Internal change to divide window/panel flags into panel flags and types.
+///                        Suprisinly spend years in C and still happened to confuse types
+///                        with flags. Probably something to take note.
+/// - 2016/09/08 (1.20.0)- Added additional helper function to make it easier to just
+///                        take the produced buffers from `nk_convert` and unplug the
+///                        iteration process from `nk_context`. So now you can
+///                        just use the vertex,element and command buffer + two pointer
+///                        inside the command buffer retrieved by calls `nk__draw_begin`
+///                        and `nk__draw_end` and macro `nk_draw_foreach_bounded`.
+/// - 2016/09/08 (1.19.0)- Added additional asserts to make sure every `nk_xxx_begin` call
+///                        for windows, popups, combobox, menu and contextual is guarded by
+///                        `if` condition and does not produce false drawing output.
+/// - 2016/09/08 (1.18.0)- Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT`
+///                        to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and
+///                        `NK_SYMBOL_RECT_OUTLINE`.
+/// - 2016/09/08 (1.17.0)- Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE`
+///                        to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and
+///                        `NK_SYMBOL_CIRCLE_OUTLINE`.
+/// - 2016/09/08 (1.16.0)- Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES`
+///                        is not defined by supporting the biggest compiler GCC, clang and MSVC.
+/// - 2016/09/07 (1.15.3)- Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error
+/// - 2016/09/04 (1.15.2)- Fixed wrong combobox height calculation
+/// - 2016/09/03 (1.15.1)- Fixed gaps inside combo boxes in OpenGL
+/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and
+///                        instead made it user provided. The range of types to convert
+///                        to is quite limited at the moment, but I would be more than
+///                        happy to accept PRs to add additional.
+/// - 2016/08/30 (1.14.2) - Removed unused variables
+/// - 2016/08/30 (1.14.1) - Fixed C++ build errors
+/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly
+/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables
+/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would
+///                        refrain from using slider with a big number of steps.
+/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the
+///                        window was in Read Only Mode.
+/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just
+///                        a hack for combo box and menu.
+/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since
+///                        it is bugged and causes issues in window selection.
+/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now
+///                        determined by the scrollbar size
+/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11
+/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection
+/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code
+///                        handling panel padding and panel border.
+/// - 2016/08/29 (1.10.0) - Added additional height parameter to `nk_combobox_xxx`
+/// - 2016/08/29 (1.10.0) - Fixed drawing bug in dynamic popups
+/// - 2016/08/29 (1.10.0) - Added experimental mouse scrolling to popups, menus and comboboxes
+/// - 2016/08/26 (1.10.0) - Added window name string prepresentation to account for
+///                        hash collisions. Currently limited to NK_WINDOW_MAX_NAME
+///                        which in term can be redefined if not big enough.
+/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code
+/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released'
+///                        to account for key press and release happening in one frame.
+/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate
+/// - 2016/08/17 (1.09.6)- Removed invalid check for value zero in nk_propertyx
+/// - 2016/08/16 (1.09.5)- Fixed ROM mode for deeper levels of popup windows parents.
+/// - 2016/08/15 (1.09.4)- Editbox are now still active if enter was pressed with flag
+///                        `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep
+///                        typing after commiting.
+/// - 2016/08/15 (1.09.4)- Removed redundant code
+/// - 2016/08/15 (1.09.4)- Fixed negative numbers in `nk_strtoi` and remove unused variable
+/// - 2016/08/15 (1.09.3)- Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background
+///                        window only as selected by hovering and not by clicking.
+/// - 2016/08/14 (1.09.2)- Fixed a bug in font atlas which caused wrong loading
+///                        of glyphes for font with multiple ranges.
+/// - 2016/08/12 (1.09.1)- Added additional function to check if window is currently
+///                        hidden and therefore not visible.
+/// - 2016/08/12 (1.09.1)- nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED`
+///                        instead of the old flag `NK_WINDOW_HIDDEN`
+/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed
+///                        the underlying implementation to not cast to float and instead
+///                        work directly on the given values.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        floating pointer number to string conversion for additional
+///                        precision.
+/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
+///                        string to floating point number conversion for additional
+///                        precision.
+/// - 2016/08/08 (1.07.2)- Fixed compiling error without define NK_INCLUDE_FIXED_TYPE
+/// - 2016/08/08 (1.07.1)- Fixed possible floating point error inside `nk_widget` leading
+///                        to wrong wiget width calculation which results in widgets falsly
+///                        becomming tagged as not inside window and cannot be accessed.
+/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and
+///                        closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown
+///                        by using `nk_window_show` and closed by either clicking the close
+///                        icon in a window or by calling `nk_window_close`. Only closed
+///                        windows get removed at the end of the frame while hidden windows
+///                        remain.
+/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to
+///                        `nk_edit_string` which takes, edits and outputs a '\0' terminated string.
+/// - 2016/08/08 (1.05.4)- Fixed scrollbar auto hiding behavior
+/// - 2016/08/08 (1.05.3)- Fixed wrong panel padding selection in `nk_layout_widget_space`
+/// - 2016/08/07 (1.05.2)- Fixed old bug in dynamic immediate mode layout API, calculating
+///                        wrong item spacing and panel width.
+///- 2016/08/07 (1.05.1)- Hopefully finally fixed combobox popup drawing bug
+///- 2016/08/07 (1.05.0) - Split varargs away from NK_INCLUDE_STANDARD_IO into own
+///                        define NK_INCLUDE_STANDARD_VARARGS to allow more fine
+///                        grained controlled over library includes.
+/// - 2016/08/06 (1.04.5)- Changed memset calls to NK_MEMSET
+/// - 2016/08/04 (1.04.4)- Fixed fast window scaling behavior
+/// - 2016/08/04 (1.04.3)- Fixed window scaling, movement bug which appears if you
+///                        move/scale a window and another window is behind it.
+///                        If you are fast enough then the window behind gets activated
+///                        and the operation is blocked. I now require activating
+///                        by hovering only if mouse is not pressed.
+/// - 2016/08/04 (1.04.2)- Fixed changing fonts
+/// - 2016/08/03 (1.04.1)- Fixed `NK_WINDOW_BACKGROUND` behavior
+/// - 2016/08/03 (1.04.0) - Added color parameter to `nk_draw_image`
+/// - 2016/08/03 (1.04.0) - Added additional window padding style attributes for
+///                        sub windows (combo, menu, ...)
+/// - 2016/08/03 (1.04.0) - Added functions to show/hide software cursor
+/// - 2016/08/03 (1.04.0) - Added `NK_WINDOW_BACKGROUND` flag to force a window
+///                        to be always in the background of the screen
+/// - 2016/08/03 (1.03.2)- Removed invalid assert macro for NK_RGB color picker
+/// - 2016/08/01 (1.03.1)- Added helper macros into header include guard
+/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to
+///                        simplify memory management by removing the need to
+///                        allocate the pool.
+/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled
+///                        will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT
+///                        seconds without window interaction. To make it work
+///                        you have to also set a delta time inside the `nk_context`.
+/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs
+/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`
+/// - 2016/07/15 (1.01.0) - Added const correctness to `nk_buffer_push' data argument
+/// - 2016/07/15 (1.01.0) - Removed internal font baking API and simplified
+///                        font atlas memory management by converting pointer
+///                        arrays for fonts and font configurations to lists.
+/// - 2016/07/15 (1.00.0) - Changed button API to use context dependend button
+///                        behavior instead of passing it for every function call.

+/* stb_image_write - v1.16 - public domain - http://nothings.org/stb
+   writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
+                                     no warranty implied; use at your own risk
+
+   Before #including,
+
+       #define STB_IMAGE_WRITE_IMPLEMENTATION
+
+   in the file that you want to have the implementation.
+
+   Will probably not work correctly with strict-aliasing optimizations.
+
+ABOUT:
+
+   This header file is a library for writing images to C stdio or a callback.
+
+   The PNG output is not optimal; it is 20-50% larger than the file
+   written by a decent optimizing implementation; though providing a custom
+   zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
+   This library is designed for source code compactness and simplicity,
+   not optimal image file size or run-time performance.
+
+BUILDING:
+
+   You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
+   You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
+   malloc,realloc,free.
+   You can #define STBIW_MEMMOVE() to replace memmove()
+   You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
+   for PNG compression (instead of the builtin one), it must have the following signature:
+   unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
+   The returned data will be freed with STBIW_FREE() (free() by default),
+   so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
+
+UNICODE:
+
+   If compiling for Windows and you wish to use Unicode filenames, compile
+   with
+       #define STBIW_WINDOWS_UTF8
+   and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
+   Windows wchar_t filenames to utf8.
+
+USAGE:
+
+   There are five functions, one for each image file format:
+
+     int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes);
+     int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data);
+     int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
+     int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
+
+     void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
+
+   There are also five equivalent functions that use an arbitrary write function. You are
+   expected to open/close your file-equivalent before and after calling these:
+
+     int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data, int stride_in_bytes);
+     int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void  *data);
+     int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
+     int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
+
+   where the callback is:
+      void stbi_write_func(void *context, void *data, int size);
+
+   You can configure it with these global variables:
+      int stbi_write_tga_with_rle;             // defaults to true; set to 0 to disable RLE
+      int stbi_write_png_compression_level;    // defaults to 8; set to higher for more compression
+      int stbi_write_force_png_filter;         // defaults to -1; set to 0..5 to force a filter mode
+
+
+   You can define STBI_WRITE_NO_STDIO to disable the file variant of these
+   functions, so the library will not use stdio.h at all. However, this will
+   also disable HDR writing, because it requires stdio for formatted output.
+
+   Each function returns 0 on failure and non-0 on success.
+
+   The functions create an image file defined by the parameters. The image
+   is a rectangle of pixels stored from left-to-right, top-to-bottom.
+   Each pixel contains 'comp' channels of data stored interleaved with 8-bits
+   per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
+   monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall.
+   The *data pointer points to the first byte of the top-left-most pixel.
+   For PNG, "stride_in_bytes" is the distance in bytes from the first byte of
+   a row of pixels to the first byte of the next row of pixels.
+
+   PNG creates output files with the same number of components as the input.
+   The BMP format expands Y to RGB in the file format and does not
+   output alpha.
+
+   PNG supports writing rectangles of data even when the bytes storing rows of
+   data are not consecutive in memory (e.g. sub-rectangles of a larger image),
+   by supplying the stride between the beginning of adjacent rows. The other
+   formats do not. (Thus you cannot write a native-format BMP through the BMP
+   writer, both because it is in BGR order and because it may have padding
+   at the end of the line.)
+
+   PNG allows you to set the deflate compression level by setting the global
+   variable 'stbi_write_png_compression_level' (it defaults to 8).
+
+   HDR expects linear float data. Since the format is always 32-bit rgb(e)
+   data, alpha (if provided) is discarded, and for monochrome data it is
+   replicated across all three channels.
+
+   TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
+   data, set the global variable 'stbi_write_tga_with_rle' to 0.
+
+   JPEG does ignore alpha channels in input data; quality is between 1 and 100.
+   Higher quality looks better but results in a bigger image.
+   JPEG baseline (no JPEG progressive).

+* @mainpage TinyCThread API Reference
+*
+* @section intro_sec Introduction
+* TinyCThread is a minimal, portable implementation of basic threading
+* classes for C.
+*
+* They closely mimic the functionality and naming of the C11 standard, and
+* should be easily replaceable with the corresponding standard variants.
+*
+* @section port_sec Portability
+* The Win32 variant uses the native Win32 API for implementing the thread
+* classes, while for other systems, the POSIX threads API (pthread) is used.
+*
+* @section misc_sec Miscellaneous
+* The following special keywords are available: #_Thread_local.
+*
+* For more detailed information, browse the different sections of this
+* documentation. A good place to start is:
+* tinycthread.h.
