Thanks for your comment, Owen. Unfortunately, I'm still too busy with other things (i.e. life). Only if I could convince my employer to give me some time to work on this (as we use a backwards hack to overcome the downscaling problems currently)... OTOH, I see Krzysztof has taken this problem more seriously than I did, so there's hope for some progress soon--thanks, Krzysztof! -- Alex _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
