* 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.
