void           gdk_region_get_rectangles (GdkRegion     *region,
                                          GdkRectangle **rectangles,
                                          gint          *n_rectangles);

And then construct the XRegion using XUnionRectWithRegion. If you
grab a mid 1.3.x series copy of GTK+, you'll find such code in
there, but it's probably easier just to redo it.

The coordinate space is bigger for GdkRegion than for an X Region, so
GdkRegion isn't internally implementation as a Region.
