I understand that NSAffineTransform can rotate an image while you're
drawing it. But is there any way to rotate an image and get a new
image? Something like:
NSImage* imageUp = [NSImage imageNamed:@"BaseImage"] ;
NSImage* imageLeft = [imageUp myRotateByDegrees:90] ;
...
How could I implement -[NSImage myRotateByDegrees] ?
(The reason is that I want images rotated in four directions to which
I can bind the 'image' binding of buttons that open/close drawers on
the bottom, top, left or right window edge.
