The color of the rest of the surface is somehow
related to the colors used in the image, although
in a way I haven't discovered as yet. I've tried
to tweak corner pixels, etc. But I haven't found
the magic pixel yet. (Any Diablo players out there?)

What does that mean? I am suppose to resize
my image before I put it on the surface? Or
that I should only put it on surfaces that have
a power of 2 size? (This actually would make
more sense to me, but I don't think it's what
you mean.) Resizing images might have serious
aspect ratio repercussions. :-)

Cheers,
