Don't think this method is used anywhere in the patch.  I seem to recall that it
was present in an earlier proof-of-concept patch to partially address potential
mismatches when scaling rects versus size objects.  Unless I missed a reference
in this CL, this should probably be pulled out for the time being.

Agreed. It's gone.
