We're currently using SDL_PIXELFORMAT_RGB24, which results in
schismtracker being blue when resized (#183).
While it's possible that RGB888 is wrong on big-endian systems, it at
least matches what we do for 16-bit (RGB565) and 32-bit (XRGB8888)
formats, so if we're wrong, we'll at least be consistently wrong.
