A short look into the docs, without actually trying anything out, says
that scanlines must be padded to a 32-bit boundary (for all data types
actually, not just 24 bits).  Does the code do that?  The docs also
say, that the colormap can be used for optimization, so it must be
initialized, even if empty.

Just some thoughts, benny
