* Headers/AppKit/NSImageRep.h: Add

-drawInRect:fromRect:operation:fraction:respectFlipped:hints: method
* Source/NSImage.m:
* Source/NSImageRep.m: Refactor drawing code from NSImage to NSImageRep.
This should cause no functionlity change, but it lets NSImageRep
subclasses implement more efficient versions of -drawInRect:fromRect:...
that don't involve the (expensive) drawing of the image in a temporary
offscreen window and then drawing from there on to the destination surface.
