Lucas Murray ca901dae30 Improved window movement around struts. Windows can be moved anywhere 
where the titlebar is still clickable even if it is outside the normal
work area. When struts are added or removed only move the windows that
cover the same area, leave all others untouched. If a strut is removed
on a xinerama screen that is not on the edge of the full desktop area
prevent the windows from being moved offscreen. Prevent struts/panels
from interfering with the movement of windows on other xinerama screens.
