Updated to use GraphicsFormat instead of DisplayMode. Updated to use ColorDepth instead of ColorMode. Improved GameWindow Exit handling, and handling of failed context creation. Improved WinGLContext creation code, to allow for FSAA support in the future. Fixed several shutdown bugs in WinGLContext and GraphicsContext. Context creation no longer relies on IGLContextCreationHack. X11GLContext is not working at the moment.
