88c30442c5 Force SDL2's render-batching 
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).

8d92bf2004 Double-buffer the OpenGL VBO 
This should reduce stalling when the OpenGL driver is still
processing the buffer when we're about to upload to it.

Hopefully, this is what was making the OpenGL ES 2.0 renderer so much
slower than the SDLTexture renderer on the Raspberry Pi 3B (SDL uses
*8* buffers). Unfortunately, I don't have access to it right now, so
I can't test this.

Now the VBO isn't resized constantly, and CreateSurface preserves
the currently-bound texture.

79886f5ae4 Add debug prints for listing SDL2 drivers 
These list what video/render/audio backends are available, and which
are currently being used.

SDL2 allows you to choose a specific video/audio driver with the
SDL_VIDEODRIVER and SDL_AUDIODRIVER environment variables,
respectively, but there's no such option for the render driver.

4e239c3175 Restore the rendering backend callbacks 
Now the SDLSurface backend survives window resizes (also triggered by
alt-tabbing while in fullscreen), and the SDLTexture backend properly
regenerates its textures after a fullscreen alt-tab in DirectX mode.

5ea356a3bd Weed out a lot of the Windows dependency 
Storytime: Cucky's original SDL2 port work involved using SDL2's
threading API to emulate the original WinAPI threading.

I can't be assed with that stuff, so I used the same trick Cucky did
for the Wii port, and hooked Organya up to the SDL2 audio callback.
This actually opens up the possibility for perfectly-synchronised
Organya playback. By that I mean, instead of needing a super
low-latency audio callback, I can have the callback synchronise its
audio mixing with Organya itself. I haven't done it yet, I plan to
soon.
