-// Picking 0.2                                                       (Thomas Bladh)
-//=================================================================================
-// A simple picking example using java/jogl. This is far from a complete solution 
-// but it should give you an idea of how to include picking in your assigment 
-// solutions.
-//
-// Notes: * Based on example 13-3 (p 542) in the "OpenGL Programming Guide"
-//        * This version should handle overlapping objects correctly.
