- Small speed improvement for 24 and 32 bpp, if internal converter is used
- Small speed improvement for generating gradients.
- Fixed RSaveXPM() to output correct xpm images.
- fixed speckles (white dots) on dithered images (bug still present on the
PowerPC architecture, because on LinuxPPC char is unsigned by default, not
signed like on the other platforms).
Bug fixed by Philip Derrin <philipd@student.unsw.edu.au>
- fixed code dependant on the order of evaluation. code like
