Title: naive implementation of SDL_DisplayFormat

`SDL_DisplayFormat` is similar with `SDL_DisplayFormatAlpha`, except for that the latter one processes the alpha channel.

But actually seems that the current version `DisplayFormatAlpha` in emscripten does not process the alpha channel, or is it processes internally? I'm not quite sure.

Please review. Thanks!
