30  Although the code is original, many of the ideas for the profiler were borrowed from
31 "Real-Time In-Game Profiling" by Steve Rabin which can be found in Game Programming
32 Gems 1.
33 
34  This code can easily be adapted to your own non-Ogre project. The only code that is
35 Ogre-dependent is in the visualization/logging routines and the use of the Timer class.
36 
37  Enjoy!
