SoXtWalkViewer — viewer component which moves the camera in a plane

       The paradigm for this viewer is a walkthrough of an architectural model. Its primary behavior is forward,
       backward, and left/right turning motion while maintaining a constant "eye level". It is also possible  to
       stop and look around at the scene. The eye level plane can be disabled, allowing the viewer to proceed in
       the  "look at" direction, as if on an escalator. The eye level plane can also be translated up and down —
       similar to an elevator.

LeftMouse: walk mode. Click down and move up/down for fowards/backwards motion. Move right and left for
       turning. Speed increases exponentially with the distance from the mouse-down origin.

       MiddleMouse - or

       Ctrl+LeftMouse: Translate up, down, left and right.

       Ctrl+MiddleMouse: tilt the camera up/down and  right/left.  This  allows  you  to  look  around  while
       stopped.

       <s>+click:  Alternative to the Seek button. Press (but do not hold down) the <s> key, then click on a
       target object.

       <u>+click: Press (but do not hold down) the <u> key, then click on a target  object  to  set  the  "up"
       direction to the surface normal. By default +y is the "up" direction.

       RightMouse: Open the popup menu.
