+Cairo - Multi-platform 2D graphics library
+https://cairographics.org
+
+What is cairo
+=============
+Cairo is a 2D graphics library with support for multiple output
+devices. Currently supported output targets include the X Window
+System (via both Xlib and XCB), quartz, win32, and image buffers,
+as well as PDF, PostScript, and SVG file output. Experimental backends
+include OpenGL, BeOS, OS/2, and DirectFB.
+
+Cairo is designed to produce consistent output on all output media
+while taking advantage of display hardware acceleration when available
+(for example, through the X Render Extension).
+
+The cairo API provides operations similar to the drawing operators of
+PostScript and PDF. Operations in cairo include stroking and filling
+cubic Bézier splines, transforming and compositing translucent images,
+and antialiased text rendering. All drawing operations can be
+transformed by any affine transformation (scale, rotation, shear,
+etc.).
+
+Cairo has been designed to let you draw anything you want in a modern
+2D graphical user interface.  At the same time, the cairo API has been
+designed to be as fun and easy to learn as possible. If you're not
+having fun while programming with cairo, then we have failed
+somewhere---let us know and we'll try to fix it next time around.
+
+Cairo is free software and is available to be redistributed and/or
+modified under the terms of either the GNU Lesser General Public
+License (LGPL) version 2.1 or the Mozilla Public License (MPL) version
+1.1.

+
+Dependencies
+============
+The set of libraries needed to compile cairo depends on which backends
+are enabled when cairo is configured. So look at the list below to
+determine which dependencies are needed for the backends of interest.
+
+For the surface backends, we have both "supported" and "experimental"
+backends. Further, the supported backends can be divided into the
+"standard" backends which can be easily built on any platform, and the
+"platform" backends which depend on some underlying platform-specific
+system, (such as the X Window System or some other window system).
+
+As an example, for a standard Linux build similar to what's shipped by
+your distro, (with image, png, pdf, PostScript, svg, and xlib surface
+backends, and the freetype font backend), the following sample commands
+will install necessary dependencies:
+
+    Debian (and similar):
+
+	apt-get build-dep cairo
+
+    Fedora (and similar):
+
+	yum install libpng-devel zlib-devel libXrender-devel fontconfig-devel
+
+Technically you probably don't need pixman from the distribution since
+if you're manually compiling Cairo you probably want an updated pixman
+as well.  However, if you follow the default settings and install pixman
+to /usr/local, your Cairo build should properly use it in preference to
+the system pixman.
+
+
+Supported, "standard" surface backends
+------------------------------------
+	image backend (required)
+	------------------------
+	pixman >= 0.30.0	https://cairographics.org/releases
+
+	png support (can be left out if desired, but many
+	-----------  applications expect it to be present)
+	libpng			http://www.libpng.org/pub/png/libpng.html
+
+	pdf backend
+	-----------
+	zlib			http://www.gzip.org/zlib
+
+	postscript backend
+	------------------
+	zlib			http://www.gzip.org/zlib
+
+	svg backend
+	-----------
+	[none]
+
+Supported, "platform" surface backends
+-----------------------------------
+	xlib backend
+	------------
+	X11			https://freedesktop.org/Software/xlibs
+
+	xlib-xrender backend
+	--------------------
+	Xrender >= 0.6		https://freedesktop.org/Software/xlibs
+
+	quartz backend
+	--------------
+	MacOS X >= 10.4 with Xcode >= 2.5
+
+	win32 backend
+	-------------
+	Microsoft Windows 2000 or newer[*].
+
+	xcb backend
+	-----------
+	XCB			https://xcb.freedesktop.org
+
+Font backends (required to have at least one)
+---------------------------------------------
+	freetype font backend
+	---------------------
+	freetype >= 2.1.9	http://freetype.org
+	fontconfig		http://fontconfig.org
+
+	quartz-font backend
+	-------------------
+	MacOS X >= 10.4 with Xcode >= 2.4
+
+	win32 font backend
+	------------------
+	Microsoft Windows 2000 or newer[*].
+
+	[*] The Win32 backend should work on Windows 2000 and newer
+	    (excluding Windows Me.) Most testing has been done on
+	    Windows XP. While some portions of the code have been
+	    adapted to work on older versions of Windows, considerable
+	    work still needs to be done to get cairo running in those
+	    environments.
+
+	    Cairo can be compiled on Windows with either the gcc
+	    toolchain (see http://www.mingw.org) or with Microsoft
+	    Visual C++.  If the gcc toolchain is used, the standard
+	    build instructions using configure apply, (see INSTALL).
+	    If Visual C++ is desired, GNU make is required and
+	    Makefile.win32 can be used via 'make -f Makefile.win32'.
+	    The compiler, include paths, and library paths must be set
+	    up correctly in the environment.
+
+	    MSVC versions earlier than 7.1 are known to miscompile
+	    parts of cairo and pixman, and so should be avoided. MSVC
+	    7.1 or later, including the free Microsoft Visual Studio
+	    Express editions, produce correct code.
+
+Experimental surface backends
+-----------------------------
+	beos backend
+	------------
+	No dependencies in itself other than an installed BeOS system, but cairo
+	requires a font backend. See the freetype dependency list.
+
+	os2 backend
+	-----------
+	Cairo should run on any recent version of OS/2 or eComStation, but it
+	requires a font backend. See the freetype dependency list. Ready to use
+	packages and developer dependencies are available at Netlabs:
+				ftp://ftp.netlabs.org/pub/cairo

+
+Compiling
+=========
+See the INSTALL document for build instructions.
+
+
+History
+=======
+Cairo was originally developed by Carl Worth <cworth@cworth.org> and
+Keith Packard <keithp@keithp.com>. Many thanks are due to Lyle Ramshaw
+without whose patient help our ignorance would be much more apparent.
+
+Since the original development, many more people have contributed to
+cairo. See the AUTHORS files for as complete a list as we've been able
+to compile so far.
