IOhannes,
Following your suggestion, I tried 0.90.1, but I've found a change in behaviour of pix_coordinate. In previous versions, the coordinates were normalized, however in 0.90.1, these seem to be related to absoulte positions of the texture. (This is on windows XP) Can you confirm?
Cheers, Andres

i cannot help you right now, but how about upgrading to gem-0.90.1 ?
