i had a look and found the following:
- - the code was always buggy :-)
- - it used fixed color offsets within pixels (e.g. "3" for "blue"), which
is simply wrong on OSX. Gem has special constants "chRed",... for
platform independent color offsets.
- - i also changed the color-type from GL_RGBA to GL_RGBA_GEM, which will
actually do the same (GL_RGBA on w32&linux and GEM_BGRA_EXT on osx) but
with less confusion :-)
