- * Do not include <SDL.h> for Windows or Android builds.
- * Most other platforms tend to include it by default, though.
- *
- * Just a few dependencies to SDL remain in the code:
- *     1.  SDL_SetGammaRamp(), in CorrectGamma()
- *     2.  SDL_SetGammaRamp(), in grGetGammaTableExt()
- *     3.  SDL_Surface* m_pScreen = SDL_SetVideoMode(...), to create context
- * Context creation can be done fine without SDL, and eventually it will be
- * nice to remove it.  However, Mac & modern Linux tends to come with SDL.
