stransky 42aec09e8a Bug 1737065 [Linux] Implement EnableRendering() / DisableRendering() for GtkCompositorWidget r=rmader
When GdkWindow is unmapped (during reparent, when GtkWindow is hidden) we need to clear Window handle at GtkCompositorWidget as it's no longer valid.
A new GdkWindow/Window is created when we're mapped again.
