Move the cursor to coordinates (x, y)on pScreen. This function is usually called via dmxPointerSpriteFuncs, except during reconfiguration when the cursor is repositioned to force an update on newley overlapping screens and on screens that no longer overlap.

+

The coords (x,y) are in global coord space. We'll loop over the back-end screens and see if they contain the global coord. If so, call _dmxMoveCursor() (XWarpPointer) to position the pointer on that screen.
