I does raise a question though - is there a way to get, at any point
in time, the list of merged rects needing update from a view *at
that point* - in other words, outside of a drawRect: call, can I
found out what has been marked for update so far? That would be
useful.
You may have to step down to CoreGraphics (CG) APIs. Perhaps
CGWaitForScreenRefreshRects or some other API would be helpful?
