[PATCH 2/2] winex11: Avoid requesting window size changes for maximized or fullscreen windows.

[Rémi Bernon]

From: Rémi Bernon

Checking the style isn't accurate, and we should check the pending state
if window is or enters maximized / fullscreen, and the current state for
windows exiting maximized / fullscreen, for which wait until the state
update is complete before requesting a new size.
