Correct clamped depth range from [0, 65535].
...
This changes a few things:
* All backends clamp the depth range and keep it positive.
* The depth rounding uniform is now properly dirtied.
* Projection is updated to translate and scale appropriately.
* Depth rounding is halved on OpenGL to account for [-1, 1] range.

Use glCopyImageSubData() when it's available.
...
There's 4 different extensions providing this functionality. NV is
supported on desktop and mobile, EXT/OES on mobile, and ARB on desktop.
Mostly these are only supported by desktop cards and NVIDIA mobile.
Good improvement in performance on NVIDIA when blit is called a lot, since
it doesn't need to rebind anything or change state. Example is in desert
city in Tales of Phantasia.

Want to get rid of direct accesses to GPUState in modules that may be reused in
my future next-gen backends, that will reformat display lists into command lists that will
then be optimized and executed, out of sync with the real GPUState.
Candidate modules that may be reused in full are Framebuffer and Depal, possibly TextureCache to some degree.

Add a conservative check that prevents alpha testing in a few cases.
...
This will become really powerful if we add some code to the vertex decoder
to check for non-full alpha in the vertices, and set gstate_c.vertexFullAlpha if none
is found (probably want to do the reverse, set it to true and clear if any non-255 alpha is found).
Alpha testing is a performance killer on many mobile GPUs so big efforts to
avoid it can be worth it.
