[R-SIG-Mac] Minor bug in Quartz sizing

[Erich Neuwirth]

I am on the road, so I cannot test this on my 27" screen at the moment.
The problem also happens without setting height and width for the quartz window.
The graphics is cut off at the bottom, it seems the engine doing the drawing gets incorrect information about the
window size.
If I set height=6 explicitly, I do not see the problem.
