great fixes there - I especially like the sinc interpolation changes. Just a remark to ImplCreateRotatedScaled, that *did* have some performance benefits, by having only *one* pass over the image. > commit 764525b39c78bfad1f6fc44a8517a565547f67cf > Author: Toma??

Want to poke me on irc for some pointers? Cheers, -- Thorsten
