It would not be difficult, but only a little tedious as you would need
to add new stub functions to cl-gd-glue.c that call the right
gdImageCreateFrom*Ptr function (available in GD2) for the file format
in question.  Also, memory handling would be an issue, but you're
certainly aware of that.

I'm not sure how many cl-gd users there are, but I'm certainly one of
them.  So please, if you add this, do it in an additive fashion :)
