Note that even this feature could be done without PerScreen (provided the
xinerma config correctly matches the physical layout) by reflecting the
layout if the screen rectangle is to the left of the average of all screen
rectangles (or to the left of a specified coordinate?).  Which would mean
also mean that the idea could be readily applied to combined layouts in a
meaningful manner even in the absence of xinerama.  (e.g. reflectLeftSide
(tall *|* tall) would be identical to (reflect tall *|* tall)
