on backends supporting GSdraw: (cairo). This means we don't have to
create a window for every call to draw an image, and gives me a 5-10x
speedup for image drawing.
* Source/NSCachedImageRep.m: Implement private method
-nativeDrawInRect:.. which is called by NSImageRep's
-drawInRect:fromRect:..., and efficiently draw the cached rep
using GSdraw:. Also make some changes so cached image reps can have a
DPI != 72.
* Headers/AppKit/NSCachedImageRep.h: New private init method that lets
you specify diferent pixel size and point size.
