   I checked out brush files from both DPaint and DPaint II.  DPaint II
brushes contain CRNG (color cycling) chunks, DPaint brushes do not.
This should not bother a correctly written IFF reader because that's
what IFF is all about.  IFF readers are supposed to just skip chunks
they don't care about or don't understand.

   It sounds like GI is not doing this, but rather is making assumptions
about the order and position of the chunks it is interested in.

   The IFF disk contains a utility called ILBMDump which converts a brush
to a C source file.  But it only writes out source for the image data,
not for the colormap.  The source is provided and could be modified to
handle additional chunks.
