commit 632a64399417c0dbdf70c96bf0de3d92c74dfc9c
Author: Jonas Ã…dahl <jadahl gmail com>
Date: Fri Nov 22 18:36:17 2019 +0100
Use paint and pick context to get framebuffer
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.
