GdkX11GLContext: Use bitblit for swap if no buffer age support

Desktop / GNOME / GTK - Alexander Larsson [redhat.com] - 6 November 2014 05:24 UTC

If buffer age is undefined and the updated area is not the whole window then we use bit-blits instead of swap-buffers to end the frame.

This allows us to not repaint the entire window unnecessarily if buffer_age is not supported, like e.g. with DRI2.
