f5b3b2e0d0 Add a basic 3DS port 
Was a lot easier than I expected. The software renderer is such a
godsend for quick-and-dirty ports.

Oddly enough, even on an old3DS, this actually almost runs at full
speed (hits around 40FPS in Mimiga Village).

There's a lot of work left to do before this is actually useable:
* There's no audio
* You can't save
* A proper hardware-accelerated renderer is needed

30ec081d7b Refactor Wii U renderer in preparation 
This is in preparation for an upscaled-framebuffer system like the
OpenGL backend has.

I wonder if it's possible to just use a shader instead, and avoid the
need for an upscaled framebuffer to make the linear filtering not
look terrible.

fe76fe6dea Big scary messy unfinished font overhaul 
This is currently hardcoded to 640x480 English builds.

What I've done is temporarily gutted the FreeType2 font renderer, and
instead introduced a system where the font is read from a
pre-rendered font atlas. This allows me to get 100% accurate font
rendering to Windows XP... because I literally created these atlases
with Windows XP.

So not only does this eliminate the issue of FreeType producing
misshapen glyphs, but it also works around the copyright issue
regarding bundling the Courier New and MS Gothic fonts with CSE2.

You see, font files can be copyrighted like any old software, however
typefaces have a lot less protection - they're basically fair-game.
IANAL, of course - look it up yourself.

I don't really want to throw away the FreeType font system since I
spent a ton of time working on it, it allows you to use other font
files, and I'll probably wind up needing it for CSE2EX. I guess I'll
just have to find some way to either have the two systems coexist, or
make it so one or the other can be selected at compile-time.

08b14fa03f Don't use upscaled framebufer if it's not needed 
This matches the SDLTexture backend.

Again, it would be really nice if this code weren't duplicated.

duplicate code there is from the SDLTexture backend.
