gdk:cairo-context, gdk:gl-context

The gdk:draw-context object is the base object used by contexts implementing different rendering methods, such as the gdk:gl-context context. It provides shared functionality between those contexts. You will always interact with one of those subclasses.

A gdk:draw-context object is always associated with a single toplevel surface.
