We can be quite a bit more efficient when pushing the pixels, I guess.
For us, we wanted alpha channels, so the background can be set
separately, this involves per-pixel calculation for the 32bit BMP
version.

First question, did yo make sure to compile with optimization? I did
not check, but the ope-coded copy loop might benefit from it.
