## Functions to support using cairo

Cairo is a graphics library that supports vector graphics and image compositing that can be used with GTK.

GDK does not wrap the Cairo API; instead it allows to create Cairo drawing contexts which can be used to draw on `GdkSurface`s.

Additional functions allow use `GdkRectangle`s with Cairo and to use `GdkRGBA`, `GdkPixbuf`, and `GdkSurface` instances as sources for drawing operations.

For more information on Cairo, please see the Cairo API reference.
