Fix: NSView

[Georg Fleischmann]

Hi,

here is a fix for NSView (CVS 2000-12-16) with two modifications to improve 
scaling:
The first change in [NSView -setFrameSize:] scales the bounds as necessary.
The second part is a little modification of [NSView -scaleUnitSquareToSize:]  
to make it behave the same like on OpenStep. (Unfortunately the specs are not  
clear in this point, and the current implementation would make sense too).

Georg

        * gui/Source/NSView.m ([NSView -setFrameSize:]):
        scale bounds, if necessary
        * gui/Source/NSView.m ([NSView -scaleUnitSquareSize:]):
        scale from bounds instead of frame (like OpenStep)
