* xrandr-capplet.c (on_clone_changed): If we turn off "mirror
screens", and if the monitors are still overlapping, lay out the
monitors from left to right so that the user will know that all
the monitors are present. Previously you had to know that you had
to un-overlap them by hand.
(lay_out_outputs_horizontally): New function.

* xrandr-capplet.c (rebuild_rotation_combo): Pass a NULL error
