[PATCH v2 0/2] MR825: winex11.drv: optimize repeated ClipCursor calls

[Jan Klötzke (＠jkloetzke)]

At least Doom 64 calls ClipCursor() with identical parameters
repeatedly, which seems to cause a considerable overhead. Together with
high polling rate mouse input this causes the game to almost freeze
while the mouse is being moved. So if the clipping did not change we can
bail out early because it will not cause any observable difference
anyway.
