That would work great for me, although it would make life easier if the
TEXTURE START line included the points making up the four corners of the
texture.

This actually wouldn't be necessary. Just put the DAT file which represents
the texture in between the TEXTURE START and TEXTURE END comments, and it
accomplishes the same thing without any compatibility issues.

Actually, JPEG doesn't have any licensing issues. I definitely agree that
GIF should be avoided due to licensing, but free decoding libraries are
available for both JPEG and PNG (in source form).
