As they require a draw context and the draw context is already bound to the surface, it makes much more sense and reduces abiguity by moving these APIs to the draw context. As a side effect, we simplify GdkSurface APIs to a point where GdkSurface now does not concern itself with drawing anymore at all, apart from being the object that creates draw contexts.
