The only other backend besides the Wii U one to use `render_target`
is the SDLTexture one.

c51a074fad Big disgusting backend rework 
We need to avoid `WindowsWrapper.h` in the backends whenever we can,
to avoid name collisions (the Wii U homebrew library) defines its own
BOOL/TRUE/FALSE, which really doesn't work with CSE2.

5b996b3459 Give glad a CMake file 
Today I learned that CMake will error if the project shares a
dependency with a nested CMake file (which could be from an
entirely-separate project that you have no control over).

I'm starting to really hate CMake.

ba6d711d3a Tick cute_spritebatch once per frame 
...As opposed to once per draw call.

This change was made because multiple draw calls can be made per
frame, or a only a handful of draw calls may be made per minute.

Since draw calls are an inconsistent metric, I just switched to
frames instead.

53c0e8470f Add an optimisation to the OpenGL renderers 
Since we track the currently-bound "source texture", we don't need
to poll the OpenGL driver for the same info.

dfacd62662 Fix text-flickering in the OpenGL renderers 
This would occur in CSE2E's options menu.

It was caused by cute_spritebatch destroying a texture atlas that
was being used by the current unflushed vertex buffer. To solve
this, we now track what textures are being used by current buffer,
and flush the buffer when the texture are about to be
modified/deleted.

As you can guess, this issue doesn't affect the SDLTexture backend,
since its batching system is half-decent.

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).
