* selecting objects has a different frontbuffer drawing handling now.

instead of drawing everything again, in all windows, it restricts to
  the active and previous active object. when there are more objects to
  be redrawn, it does a normal swapbuffers.
  Result is it all redraws & selects a lot faster in complex scenes

* Little fix in "BallTable" routine when moving mouse vertical out of
  the 3d window.
