Direct3D 11 backend

[LunaMoo]

Sometimes Henrik's too fast to say things aren't implemented, that info get's outdated quickly.

D3d11 backend is pretty much finished and aside from some minor stuff(like post process which autotranslation that wasn't merged yet and has problems with some effects) actually better than OGL.
On older windows versions(pre 8.1?) it requires D3DCompiler_47.dll(part of windows SDK, Visual Studio 2015 includes it) which PPSSPP doesn't include yet ~ possibly will have to in the future.

As for magical performance increases it's at least a few % lighter, might not matter much for running games on desktops(probably will on windows mobile), but always a bit more eco friendly when you sum up all electricity wasted on those few % among many users playing games, at least people who live in more polluted places should care about that.

Also on AMD gpu's especially newer ones it's pretty much required nowadays with broken OGL drivers bugging certain effects in some games, d3d11 is perfect solution.
