Use paint and pick context to get framebuffer

Browse Source 
Mutter and Clutter was changed to pass around the current target
framebuffer via the paint context instead of via the deprecated Cogl
framebuffer stack.

The framebuffer stack has also been removed from Cogl so change to use
the one in the paint context instead.
