7dd0d242e2 Load the clut only using LOADCLUT, not every tex. 
This is a small optimization, and should match PSP behavior better.
It also allows us to hash the clut and convert colors less often.

342ae6c322 Reuse the fullhash when it triggers a reload. 
Instead of hashing it again a few microseconds later...

4a30221c95 Ignore texfunc RGBA when texture is full alpha. 
This allows us to skip some work in the fragment shader.

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.

3c0ed69fd2 Improve GPU invalidation interface, check fonts. 
When a font is rendered, tell the GPU about it, but don't rehash.

This not only improves perf (less hashing) but makes font changes more
immediate (no deferred hashing.)  But only if they use sceFont.

995ab510e9 Optimize alpha-only CLUTs, common for fonts. 
This optimizes the case where fonts are drawn using animation (common in
RPGs, for example), and textures have to be decoded over and over.

Could probably be faster with SIMD.

bd692ddf66 Check for low GPU memory and try to disable cache. 
This may help with phones and even desktops without much VRAM/RAM.
Normally OpenGL will copy between them, though, so it should not happen
often, especially not on desktops.

5b970d76e3 Use SSE2 in the texture hashing function. 
Speeds it up significantly, but only when it's called a lot.

02c88b9517 Add a secondary texture cache again. 
This time, only used when invalidations happen several times, but not
too often, and still hashes the entire texture.

57c7b21640 Convert colors before applying clut, not after. 
No reason to build it wrong and fix it afterward.

f6287cb33d Resize the tex buffers to the larger of w/bufw. 
Since it's rearranging, it needs the larger, and it might be in place too.

394a8eaf9e Small optimization to typical 4-bit textures. 
These aren't used that often, but this makes them a bit faster.

It also looks cleaner, imho.

6a7722283c Hash textures using cityhash rather than adding. 
It should be more accurate, and for some games is faster.
For most it seems not hugely different.
