I would imagine that for frame positioning, absolute scaled would be the 
default, as top and left frame parameters should also be absolute scaled.

To pass absolute unscaled to an external program or to position on absolute 
unscaled a special functions would be needed.  But I don't think a function 
that gives window edges is the place to do that.
