  Sure.  It still does, right?  Snapping still works.

  I thought that it might have something to do
with smooth rotation from the blue handle, but if you are rotating a
normal sized object via the blue handle, one pixel move translates to
way more than 0.01 degrees, so having closeTo: there doesn't help.
