[PATCH 0/2] MR7014: winex11: Move GL/VK offscreen if the clipping region is NULLREGION.

[Rémi Bernon (＠rbernon)]

NULLREGION means that the entire window should be clipped out, and its
children displayed instead. The change broke some offscreening decisions
when both parent and children have a GL drawable created but drawing
actually happens on the child window.
