07e4e3b971 Offload texture coord transformation to GPU 
I imagine this isn't too helpful when the GPU is the bottleneck, like
on my Raspberry Pi.

Duplicate junk. If they're that important, they can go in the game,
not the backends.

eadc04e46e Bump StartDirectDraw fix to FIX_MAJOR_BUGS 
I was debugging GLFW earlier, and this fix wasn't being enabled.
FIX_BUGS should be for aesthetic bugs that only affect gameplay, not
ones that affect fundamental stability.

6b18ec91be Replace LockSurface with UploadSurface 
The old locking/unlocking API was plain inefficient. Soon I'll move
upscaling to the backend anyway, to minimise the overhead where
possible.

Currently only the software renderer has been updated.

Saves a little memory in some cases. It's the backend's job to decide
if this is a problem or not, and pad it if it has to.

7bc028f5d8 Enable window-resizing in the SDLTexture renderer 
Previously, the window was a fixed size just like the original.

This change highlights a weird issue in CSE2: this doesn't exactly
match the behaviour of the original game, so why did I change it?
Simple: monitors had much lower pixel-densities back in the early
2000s, meaning that 320x240 and 640x480 weren't as laughably small as
they are today.

I like to think of CSE2's portable branch as Cave Story's equivalent
to Chocolate Doom: the point isn't to replicate the game's behaviour
100% - that's the accurate branch's job - no, the point of the
portable branch is to replicate the *experience* of the game, as it
was back in 2004. This means no commically-small windows.

This is the same reason font anti-aliasing is disabled, even in
versions of Windows later than XP.

Sidenote: the OpenGL3/OpenGLES2 renderers already had this feature,
but they used linear-filtering, causing the screen to be extremely
blurry in 320x240 mode. This renderer uses a better method, which
does apply slight blurring at the edges of pixels at resolutions
that aren't an exact multiple of 320x240/640x480, but otherwise it
resembles nearest-neighbour. This is way nicer to look at, and fits
the game's aesthetic. This feature will be ported to the other
renderers soon.
