I suspect this is because there's a call to gdk_color_alloc for each pixel
in the xpm. The xpm loader should probably be rewritten to use a color context
instead. As I'm guilty of writing the original slow version, I guess
I'll have to take a hack at it soon; it shouldn't be too hard. If you're in
a hurry I guess you'll have to take a look at imlib.

IIRC, Quartic is working on such a widget for the GNOME project. I dont know
if this will be included in gtk+.
