e3cd7ce353 Add glyph-batching to OpenGL renderer 
Unfortunately, sub-pixel font rendering had to go. It wasn't portable
anyway (not every display is an LCD with R->G->B ordering).

788697dc5d Fix a possible hang in the audio mixer 
It was likely a race condition between the game thread writing to
'organya_timer', and the audio thread reading it.

...I really need to rethink the API for this Organya-synchronisation
thing.

e33bd9c8f9 Fix visual artefacting on the Pi 
I'm not sure why there was linear filtering when I was rendering at
1:1 pixel ratio, but it did happen. This fixes it by forcing
nearest-neighbour. The artefacting was caused by the linear filtering
blending with pixels outside the specified texture coordinates,
creating lines around everything.

Fun fact: the framebuffer technique CSE2 uses is demanding on the Pi
(1278x720 runs at 60 FPS when the framebuffer is forced to 852x480,
even though all the internal rendering is still 1278x720). I guess
rendering those extra 920160 pixels really takes its toll.

99a8b2bd18 Improve OpenGL performance on the Raspberry Pi 
Apparently 2 VBOs wasn't enough. This bumped the framerate from 13FPS
to 20FPS in a stress-test (CSE2E at 1704x960 on a Raspberry Pi 3B
in X11 with the KMS OpenGL driver).

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.

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.
