[Ohrrpgce] Android port

Tue Jun 4 06:26:38 PDT 2013

Saving/loading works fine. Sounds work (but no music, which is a known
limitation).

I didn't see any audio artifacts, and I recorded a short (fuzzy) video
to showcase this:
http://youtu.be/NiaQF-Z77VE

If you're getting artifacts on hardware, perhaps it's a delay between
SDL_Init (or GL_Init) and the code to draw frame 0? Perhaps you could
modify the OHR to clear the screen (to black) immediately after
SDL_Init (or GL_Init; I'm not sure exactly how SDL handles this).

I'll run the other tests you listed later.
