2adfef0035 Got Backend_Blit to go from 17% CPU usage to 11% : 
- used __builtin_expect to get a 8.5% performance improvement
- used #pragma omp for to get a 30% performance improvement

d4004fe99a Store glyph pixels as chars, not floats 
Smaller memory footprint, and probably-insignificant performance
impact.

59a8c2617f Tweak some variable naming 
The enhanced branch calls them the 'internal *screen* width/height',
which I think is more appropriate.

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).

3f8ead09d6 Renderer backend simplification part 1: Draw.cpp and Software.cpp

e094f2ff68 Renderer backend fixes 
Surface-to-surface blits were broken (would draw to screen instead),
and the SDLSurface backend wouldn't even compile.

You know, I thought I tested each backend when I made those changes
to the API...

145864cf2d Added sanity checks to the backends 
This fixes the Texture backend bug that made the program take forever
to shut down:

The problem was that the font system would try to load a glyph that's
0 pixels wide/tall (likely the space character), which SDL2 didn't
like, so it would fail to allocate the texture, causing
Backend_CreateSurface, and by extension Backend_CreateGlyph, to
return a NULL. Later, upon shutdown, the font system would pass this
NULL to Backend_FreeGlyph, causing NULL pointer dereferences that
make the program take forever to shut down.

Personally, I think passing NULLs to the backend is valid behaviour,
so I've added a bunch of sanity checks to make sure they're never
dereferenced.

6d385e674f Font refactor part 1: Software 
With this, font blitting is handled by the rendering backend, paving
the way for hardware-accelerated font drawing in the accelerated
backends.

These only really happen when you use exclusive fullscreen and
alt-tab out. Or, at least, it does on Windows with SDL2 in DirectX
