	(ReadImage): lets get the offset right.  This will let transparent
	gifs work.


Right now, gifs with transparency, both interlaced and non-interlaced,
seem to work perfectly fine.  I haven't tried grayscale gifs yet, and I
seem to be getting offset in my RGB buffer with non-alpha gifs. )-:
This leads to pretty, but incorrect, images.

        * src/io-jpeg.c: Added first cut at progressive jpeg loading.
        Currently does not handle either progressive jpeg files (jpeg
        files with multiple scans at different quality settings), but
        I plan on adding this support soon. These are fairly rare in
        my experience, so it shouldn't slow people down too much.
        Grayscale jpegs also don't work but that should be easy to fix.

1999-10-29  Michael Fulbright  <drmike@redhat.com>

        * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
        load the image handler when we determine the image type.

        * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
        previously static function load_image_handler () to
        a public function gdk_pixbuf_load_module (). It is needed in
        gdk-pixbuf-loader.c to load image handler modules.  This function
        is different from gdk_pixbuf_get_module (), which only returns
        a reference to the required handler, because it actually loads
        the handler into memory. Both actions should possibly be combined
        in a convenience function since one w/o the other doesn't seem to
        make much sense.
