      Description

      Visuals which are placed under the ViewPlatform appear to jitter if the
      ViewPlatform is mounted far away from the View World.

      In the attached testcase, there is a terrain type wireframe grid mounted under
      the ViewPlatform which itself is stationed at 50 units from the World origin.
      The grid is un-pickable and is rigidly attached to the ViewPlatform; however,
      upon rotating the scene by pressing the left mouse button, I notice that the
      grid jitters very perceptibly. This leads to rather annoying artifacts in a HUD.

      To test do:

      1. deflate the attached vpjitter.jar
      2. javac *.java
      3. java VPJitter

      Press the left mouse button and move the mouse continuously to observe the
      jittering effects.
