Should remove the performance impact of #8994 which is bigger than

f1c06d25ea Switch to old-style depth in OpenGL.

accuracy problems when specifying the values to OpenGL.

529abd7db4 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.

Fixes Phantasy Star Portable 2 without the need for a game-specific hack.

fbc4b4e7a1 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.

Henrik Rydgard
2430c283a5 More GPU cleaning, removing uses of GPUState.h where not needed. 
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.

1f51fe7843 d3d: Avoid rewriting textures, just swizzle. 
Luckily A is in the same place and the same width, so we can do this for

4c1c694d4b Use flags to avoid hashing textures when unchanged.

b174996c1c 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.

711d3ff52c Speedup a few 2D games on mobile by eliminating the alpha test in some conditions

6360fcb0ae Add some stats to get some idea of much alpha tested drawing we do.

dfb91d4532 Track number of GPU commands executed per call level. 
This is to get an idea if it would be beneficial to compile and cache display lists. Looks like it would be for some games, for example in GTA it's often 20k/80k/20k commands per frame - that is 100k executed commands per frame that could potentially just be executed instead of interpreted. Likewise in Wipeout. Of course, this means yet another cache with invalidation issues etc..

cb217189c5 Keep track of whether a texture has alpha. 
This way we know what sorts of blending we even have to do.  Commonly,
textures don't have any real alpha.

Not yet used for anything.

85a23dac63 Avoid framebuffer lookups for repeated prims. 
There are usually many prims per framebuffer.  This cuts time spent in
SetRenderFramebuffer() from 1% to 0.13% (although a bit more time in
ExecuteOp, not much.)

bc15617392 Make un-buffered rendering much smarter, removing flicker. 
This turns it into a very viable option for many games. You do lose some FX
but it can as a result even be used as a workaround for the massive glow
in Wipeout...
