/* This is a workaround.  Since scalars are contained within a tkpath
   group, and since tkpath groups don't have coords, we have to fudge
   things with regard to Pd-l2ork's normal *_displace_withtag functionality.
   (Additionally, we can't just fall back to the old displace method
   because it too assumes the canvas item has an xy coord.)

   We draw the selection rect but don't add the scalar to the
   "selected" tag.  This means when Pd-l2ork issues the canvas "move"
   command, our scalar doesn't go anywhere.  Instead we get the callback
   to scalar_displace_withtag and do another workaround to get the
   new position and feed it to the scalar's matrix.

   This creates a problem with gop canvases, and yet _another_ partial
   workaround.  We need the global variable below to let the so that
   we can figure out whether the displace call is coming from the scalar
   itself or from a parent graph.  This means scalars won't currently
   respond properly in nested gops.  (I think that requires a window
   item on the canvas to replace the current gop rect.)

     |      This group is not configurable by the user.  This

   draw   - various drawing instructions (rectangles, paths, etc.).
            Each has its own matrix and options that can be

   The tag "blankscalar" is for scalars that don't have a visual
