The last patch I sent does homogenous zooming, has no more (known) floating issues (I am not gonna bet about floats, what is more, not gonna bet about Gimp either, I saw some warnings about aliasing in other parts, and I already had enough with C guts) and is small, it just fits in place with the old code instead of more deep changes.

So in the end both do a list of presets. Main difference is that mine is simetrical (that can be good or bad) and uses a typical search system. BTW, the CLAMP should be 255 or 256?

Problems solved... what do you mean with different set? Both can be adjusted, that was one of the differences from my first to second version, the table changed. GSR
