Remember the drawable is server-side and in a format specific to your
video card. So it's hardly a convenient representation for this kind
of thing.

That said, you might use the GdkPixbuf library and
gdk_pixbuf_get_from_drawable(), then you can use libpng to save the
RGB data. GTK 2 beta (1.3.4) contains a gdk_pixbuf_save() function you
could copy, but I don't think gdk-pixbuf 1.0 contains it.
