Raw Normal View History

libimg: 1. tiff (baseline) support 2. pnm (portable anymap) bilevel, grayscale (8bpp), pixmap (24bpp) support 3. xcf: optional layer merging/blending with sse (default is mmx) 4'. new formatting for my old code. more readable for now git-svn-id: svn://kolibrios.org@2388 a494cfbc-eb01-0410-851d-a64ba20cac60
