Added some code to stop producing interpolation frames if the scene has

already reached its scroll target. This keeps BS2 from using all available
CPU time all of the time.

It may still be that we need a mechanism for throttling the frame rate when
the scene is moving towards a scroll target, but my computer isn't really
fast enough to test that.

Two other bugs fixed in the process:

* I think the last frame of the render cycle was rendered, but not
  displayed. If so, that should be fixed now.

* I discovered that there are cases where we do need to clear the screen
  (e.g. at the "Meanwhile..." message when George has found out about the
  Glease Gallery), so I've re-enabled the function and disabled it in the
  render cycle.
