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 [class@Gdk.Surface]s.

Additional functions allow use [struct@Gdk.Rectangle]s with Cairo and to use [struct@Gdk.RGBA], GdkPixbuf, and [class@Gdk.Surface] instances as sources for drawing operations.

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