commit 79d2d0e40d35c2b22b4e9005486af6823b09c0e0
Author: Benjamin Otte <otte redhat com>
Date: Sun Nov 13 16:16:39 2016 +0100
snapshot: Add gtk_snapshot_render_background()
and gtk_snapshot_render_frame() to be direct replacements for the
old gtk_render_*() functions.
Use them to replace Cairo usage completely in gtk_window_snapshot().
