Force SDL2's render-batching

Browse source 
SDL2 will implicitly disable batching if we force a specific
rendering driver (apparently the user setting SDL_RENDER_DRIVER
counts too) for backwards-compatibility with older programs that use
their own rendering side-by-side with SDL2's. We don't do that,
though, so this commit forces SDL2 to use batching if it's available
(2.0.10 and onwards).
