 /**

+ * @Short_description: Functions to support using Cairo
+ * @Title: Cairo Interaction
+ *
+ * <link href="http://cairographics.org";>Cairo</link> is a graphics
+ * library that supports vector graphics and image compositing that
+ * can be used with GDK. Since 2.8, GTK+ does most of its drawing
+ * using Cairo.
+ *
+ * GDK does not wrap the Cairo API, instead it allows to create Cairo
+ * contexts which can be used to draw on #GdkDrawables. Additional
+ * functions allow to convert GDK's rectangles and regions into
+ * Cairo paths and to use pixbufs as sources for drawing operations.
