-<p><a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-t" title="cairo_pattern_t"><span class="type">cairo_pattern_t</span></a> is the paint with which cairo draws.
-The primary use of patterns is as the source for all cairo drawing
-operations, although they can also be used as masks, that is, as the
-brush too.</p>
-<p>A cairo pattern is created by using one of the many constructors,
-of the form
-<code class="function">cairo_pattern_create_<span class="emphasis"><em>type</em></span>()</code>
-or implicitly through
-<code class="function">cairo_set_source_<span class="emphasis"><em>type</em></span>()</code>
-functions.</p>

-<p>Adds an opaque color stop to a gradient pattern. The offset
-specifies the location along the gradient's control vector. For
-example, a linear gradient's control vector is from (x0,y0) to
-(x1,y1) while a radial gradient's control vector is from any point
-on the start circle to the corresponding point on the end circle.</p>
-<p>The color is specified in the same way as in <a class="link" href="cairo-cairo-t.html#cairo-set-source-rgb" title="cairo_set_source_rgb ()"><code class="function">cairo_set_source_rgb()</code></a>.</p>
-<p>If two (or more) stops are specified with identical offset values,
-they will be sorted according to the order in which the stops are
-added, (stops added earlier will compare less than stops added
-later). This can be useful for reliably making sharp color
-transitions instead of the typical blend.</p>

-<p>Adds a translucent color stop to a gradient pattern. The offset
-specifies the location along the gradient's control vector. For
-example, a linear gradient's control vector is from (x0,y0) to
-(x1,y1) while a radial gradient's control vector is from any point
-on the start circle to the corresponding point on the end circle.</p>
-<p>The color is specified in the same way as in <a class="link" href="cairo-cairo-t.html#cairo-set-source-rgba" title="cairo_set_source_rgba ()"><code class="function">cairo_set_source_rgba()</code></a>.</p>
-<p>If two (or more) stops are specified with identical offset values,
-they will be sorted according to the order in which the stops are
-added, (stops added earlier will compare less than stops added
-later). This can be useful for reliably making sharp color
-transitions instead of the typical blend.</p>

-as Coons patch meshes (type 6 shading in PDF) and Gouraud-shaded
-triangle meshes (type 4 and 5 shadings in PDF).</p>
-<p>Mesh patterns consist of one or more tensor-product patches, which
-should be defined before using the mesh pattern. Using a mesh
-pattern with a partially defined patch as source or mask will put

-<p>A tensor-product patch is defined by 4 Bézier curves (side 0, 1, 2,
-3) and by 4 additional control points (P0, P1, P2, P3) that provide
-further control over the patch and complete the definition of the
-tensor-product patch. The corner C0 is the first point of the
-patch.</p>
-<p>Degenerate sides are permitted so straight lines may be used. A
-zero length line on one side may be used to create 3 sided patches.</p>

-<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-begin-patch" title="cairo_mesh_pattern_begin_patch ()"><code class="function">cairo_mesh_pattern_begin_patch()</code></a>, then <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-move-to" title="cairo_mesh_pattern_move_to ()"><code class="function">cairo_mesh_pattern_move_to()</code></a>
-to specify the first point in the patch (C0). Then the sides are
-specified with calls to <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-curve-to" title="cairo_mesh_pattern_curve_to ()"><code class="function">cairo_mesh_pattern_curve_to()</code></a> and
-<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-line-to" title="cairo_mesh_pattern_line_to ()"><code class="function">cairo_mesh_pattern_line_to()</code></a>.</p>
-<p>The four additional control points (P0, P1, P2, P3) in a patch can
-be specified with <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-set-control-point" title="cairo_mesh_pattern_set_control_point ()"><code class="function">cairo_mesh_pattern_set_control_point()</code></a>.</p>
-<p>At each corner of the patch (C0, C1, C2, C3) a color may be
-specified with <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-set-corner-color-rgb" title="cairo_mesh_pattern_set_corner_color_rgb ()"><code class="function">cairo_mesh_pattern_set_corner_color_rgb()</code></a> or
-<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-set-corner-color-rgba" title="cairo_mesh_pattern_set_corner_color_rgba ()"><code class="function">cairo_mesh_pattern_set_corner_color_rgba()</code></a>. Any corner whose color
-is not explicitly specified defaults to transparent black.</p>
-<p>A Coons patch is a special case of the tensor-product patch where
-the control points are implicitly defined by the sides of the
-patch. The default value for any control point not specified is the
-implicit value for a Coons patch, i.e. if no control points are
-specified the patch is a Coons patch.</p>
-<p>A triangle is a special case of the tensor-product patch where the
-control points are implicitly defined by the sides of the patch,
-all the sides are lines and one of them has length 0, i.e. if the
-patch is specified using just 3 lines, it is a triangle. If the
-corners connected by the 0-length side have the same color, the
-patch is a Gouraud-shaded triangle.</p>
-<p>Patches may be oriented differently to the above diagram. For
-example the first point could be at the top left. The diagram only
-shows the relationship between the sides, corners and control
-points. Regardless of where the first point is located, when
-specifying colors, corner 0 will always be the first point, corner
-1 the point between side 0 and side 1 etc.</p>
-<p>Calling <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-end-patch" title="cairo_mesh_pattern_end_patch ()"><code class="function">cairo_mesh_pattern_end_patch()</code></a> completes the current
-patch. If less than 4 sides have been defined, the first missing
-side is defined as a line from the current point to the first point
-of the patch (C0) and the other sides are degenerate lines from C0
-to C0. The corners between the added sides will all be coincident
-with C0 of the patch and their color will be set to be the same as
-the color of C0.</p>
-<p>Additional patches may be added with additional calls to
-<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-begin-patch" title="cairo_mesh_pattern_begin_patch ()"><code class="function">cairo_mesh_pattern_begin_patch()</code></a>/<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-end-patch" title="cairo_mesh_pattern_end_patch ()"><code class="function">cairo_mesh_pattern_end_patch()</code></a>.</p>

-<p><a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-type-t" title="enum cairo_pattern_type_t"><span class="type">cairo_pattern_type_t</span></a> is used to describe the type of a given pattern.</p>
-<p>The type of a pattern is determined by the function used to create
-it. The <a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-create-rgb" title="cairo_pattern_create_rgb ()"><code class="function">cairo_pattern_create_rgb()</code></a> and <a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-create-rgba" title="cairo_pattern_create_rgba ()"><code class="function">cairo_pattern_create_rgba()</code></a>
-functions create SOLID patterns. The remaining
-cairo_pattern_create functions map to pattern types in obvious
-ways.</p>
-<p>The pattern type can be queried with <a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-get-type" title="cairo_pattern_get_type ()"><code class="function">cairo_pattern_get_type()</code></a></p>
-<p>Most <a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-t" title="cairo_pattern_t"><span class="type">cairo_pattern_t</span></a> functions can be called with a pattern of any
-type, (though trying to change the extend or filter for a solid
-pattern will have no effect). A notable exception is
-<a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-add-color-stop-rgb" title="cairo_pattern_add_color_stop_rgb ()"><code class="function">cairo_pattern_add_color_stop_rgb()</code></a> and
-<a class="link" href="cairo-cairo-pattern-t.html#cairo-pattern-add-color-stop-rgba" title="cairo_pattern_add_color_stop_rgba ()"><code class="function">cairo_pattern_add_color_stop_rgba()</code></a> which must only be called with
-gradient patterns (either LINEAR or RADIAL). Otherwise the pattern
-will be shutdown and put into an error state.</p>
-<p>New entries may be added in future versions.</p>
