Subject: [PATCH] cocoa: breaking forceful Window update to cause invalidation
 instead of the immediate redrawing. The forceful redrawing is exteremely slow
 in Cocoa. This potentially might introdcue some bugs, though helps to imrove
 the performance dramatically (in places where UpdateWindow() is heavly
 (ob)used)
