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.

2adfef0035 Got Backend_Blit to go from 17% CPU usage to 11% :

- 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

59a8c2617f Tweak some variable naming 
The enhanced branch calls them the 'internal *screen* width/height',

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...
