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.

f8a40318a2 OpenGL fixes and optimisations 
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.

a0eb646a1f Add ability to lock certain parts of a surface 
This avoids conditional jumps based on uninitalised memory, and
should be faster, and should be lighter on memory.

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.

5da3b72fca Split glyph surface creation and pixel upload 
When DirectX-SDL2 loses its device, it doesn't lose its textures,
just their contents, so we shouldn't remake the textures when we
regenerate the glyphs (that's coming next commit).

d47f683491 Ported the Windows version's surface regeneration 
Has the same imperfections: if you regenerate the surfaces while a
text box is open (and while using Courier New I guess), the text will
regenerate with smaller spaces.

Surface-to-surface blits were broken (would draw to screen instead),
