* Source/NSButtonCell.m (-drawImage:withFrame:inView:): Align

Browse source 
the point at which the image is drawn to the nearest pixel.

r32895 which reimplemented -[NSImage composite..] methods
on top of -[NSImage draw...] methods means that drawing
images with -compositeToPoint: no longer pixel-aligns
the image automatically. The new behaviour matches
Cocoa, however.
