Custom PPSSPP shaders

[guest.r]

Hello everybody!

I post here regarding the AA shader 4.o mr. Shinra would like to test. Hey no problem, it's a very fine xBRZ support shader and it can do nice downsampling AA also (the internal resolution should be set to 8x for example).

The "scale" variable in the fragment file should be edited to suit specific tastes, but i guess i found a good compromise with 7x.

(Darn, the cartoon shader could use an update also).

PS: IMO it could replace the AA-color shader and the HQ one.
They are a bit outdated.

Great job on everything anyway and keep up the good work.

Edit: updated shaders can be downloaded from the nex page.
