Yes, we are interested. I'd really like to get rid of the random number generator in the gradient blend code. It is simply way too slow and gradient blends are a rather frequent operation. Please have a look at the current code in CVS (will take a day for anoncvs to catch up). It is a lot more readable and should allow for easy replacement of the RNG by a dither matrix. Sven
