While this might appear to be an easier solution,
it not only takes all the fun out of a hyper-technical
programming operation, it introduces a whole host of
new problems that have to be solved. For one, reducing
your image to the resolution of the surface will make
that image awfully ugly. (I can't really think of a
way to solve this limitation, to tell you the truth.)

Another problem would be matching the image to a
particular location on the surface. This, presumably,
is the whole point of putting the image on there in
the first place. Getting the correspondence correct
would be an awfully tedious process, it seems to me,
and could only really be accomplished easily if the
surface and image data had the same aspect ratio.
Pretty rare in practice, I think.

Cheers,

David
