          Create the 3D UIRectangle.  This allows
          the DrawingSurface to be rotated relative
          to the screen, allowing a 3D aspect to
          the DrawingSurface.  The Surface
          can still be interacted with, so Buttons,
          Menus, etc. all will still function
          normally.

          -setPoint(Pnt3f): Determine the location
          of the UIRectangle in 3D space.  Keep
          in mind that (0,0,0) is located 
          directly in the center of the sceen.
          (For our purposes it is the center 
          of the tori.) The point is located
          on the lower left corner of the 
          rectangle.
          -setWidth(float): Determine the Width
          of the UIRectangle.  This may 
          physically appear different depending
          on where the UIRectangle is placed
          as above (due to it being located
          further away, etc).
          -setHeight(float): Determine the Height
          of the UIRectangle.  This may 
          physically appear different depending
          on where the UIRectangle is placed
          as above (due to it being located
          further away, etc).
          -setDrawingSurface(DrawingSurface):
          Determine what DrawingSurface is
          drawn on the UIRectangle.  This 
          will typically be the main
          DrawingSurface, however, multiple
          DrawingSurfaces can be used with
          multiple UIRectangles.
