/*
* Main.cpp
*
* Main program driver for the SDL port.
*
* To Do Before Next Release
* -------------------------
* - Add UI keys for balance setting?
* - 5.1 audio support?
* - Stretch video option
*
* Compile-Time Options
* --------------------
* - SUPERMODEL_WIN32: Define this if compiling on Windows.
* - SUPERMODEL_OSX: Define this if compiling on Mac OS X.
* - SUPERMODEL_DEBUGGER: Enable the debugger.
* - DEBUG: Debug mode (use with caution, produces large logs of game behavior)
