That works fine if you have enough space in memory for the bitmap, and if 
you are willing to have all scaling done at the bitmap level.  In general 
this results in some ugly-looking artifacts if the scaling ratio is not a 
"nice" one, as you can see by using MacPaint and stretching and squashing 
images on the screen.
