//  Class: SoXtPlaneViewer
//
//  Plane Viewer - allows the user to move the camera in a plane, zoom in
//      and out, as well as rotate the viewing plane.
//
//      Keys used by this viewer:
//      -------------------------
//
//     Left Mouse: Dolly in and out (gets closer to and further away from the
//     object).
//
//     Middle Mouse:
//     Ctrl + Left Mouse: Translate up, down, left and right.
//
//     Ctrl + Middle Mouse: Used for roll action (rotates around the viewer
//     forward direction).
//
//     <s> + click: Alternative to the Seek button. Press (but do not hold down)
//     the <s> key, then click on a target object.
//
//     Right Mouse: Open the popup menu.
