Re: CGConfigureDisplayOrigin

The actual position a display is placed at will be as close as 
possible to the requested location without overlapping or leaving a 
gap between displays.  One display must always have an origin of (0,0).

The configuration code will take the requested layout information, 
and if it does not meet the requirements for tiling and maintaining 
one display at (0,0), will adjust the requested layout as needed to 
meet these requirements.
