I think I am back online I think. I want to wrap up the new implementation of BBox_Cubic_Check. As we discussed, the integer Bezier split algorithms are not accurate, with the lowest two bits being random. Freetype lives with this. So I wonder what's the expectations for the BBox calculations? Do we really need accuracy better than 2 bits? _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
