While using SetOrigin is a lovely idea, this is only one of the managers that
assumes the origin is 0.  The Window Manager routine DrawGrowIcon also assumes
the origin is 0, as does all of TextEdit.  If you must use SetOrigin, one
strategy that works is to only use it when you actually draw (in your update
routine, mostly) and immediately set it back to 0,0 after you draw your objects,
but before you call DrawControls and DrawGrowIcon.
