When using a window manager, such as metacity, that draws windows while
resizing, GNUstep draws each view in the window. This consumes too much CPU
and causes flickering. This is problem mainly for windows with complex views
with lots of drawing inside, including text compositing.

This can be avoided if gnustep has implemented NSView methods:

– inLiveResize

– viewWillStartLiveResize

– viewDidEndLiveResize
