I just ran a test against 1.2, and picking under a DCS with
uniform and nonuniform scales works for me. You need to be
aware that the location (PFQHIT_POINT) of the hit is
returned in object coordinates (i.e. unscaled). So if you
want the result in scene coordinates, the location must be
transformed (using PFQHIT_XFORM). However, this would not
explain the absence of a hit.
