[4eyes] Optimization problem

[Cha Lee]

Hey folks,

I've got a code bottleneck that I could use some help on. For
compatibly reasons, I need to copy an N*M image to a S*S image. The
first image is a rectangular image but the second is a power of two
image. What I'm doing now is going pixel by pixel on the second image,
find the correct pixel coordinate on the first image, and copying over
the color information. Basically pixel by pixel copy. This is
obviously killing my performance.

Any suggestions?
