Does drawInRect: do something differently?

-compositeToPoint:... and -drawInRect:... methods of NSImage do behave differently. -compositeToPoint: is faster, since it doesn't honor the current transformation matrix when rendering the image.[1] -drawInRect will take into account any scaling, rotation, etc.

-jcr
