[SDL] SDL_PollEvent()

[pixel fairy]

the whole point was making the app light on the cpu. i ended up using
SDL_Delay like this

while(1) {
     check_events()
     update_state()
     draw(backbuffer)
     delay()
     SDL_GL_SwapBuffer()
}

i think that swapping buffers at frame update time would be
more consistant since the time to draw is more variable, but
it probably doesnt make much differnce. havent tested this yet.
