I could only test the G-M because I don't have an Amber-Blue.

[Tilka]

Please drop the merge commit; we won't merge it like this.

Are those mat3 supposed to be some sort of aligned? Looks a bit random to me.

[Sonicadvance1]

Are we even able to use these constants? They are copywritten under "All rights reserved" which I think we aren't allowed to distribute without explicit say from the original author to do so, which breaks GPL?

[degasus]

Mathematic constants aren't copyright-able, so they are fine.

[degasus]

Are those shaders tested on both D3D and OGL? iirc they have some other default meaning of row vs vector based matrices :/

[Tilka]

You'll have to rebase, not merge.

[LenaWil]

I thought I did and I'm sorry for all the garbage. Can I start over?

[Tilka]

If you mean open a new PR, there's no need for that. Once you get it right locally, you just need to force-push. If you need help, join #dolphin-dev on freenode.

[LenaWil]

@Tilka done :)
@degasus the shaders are for and tested on OpenGL. Does the Direct3d backend have support for Post-Processing Effect shaders?
@BhaaLseN It's based on Dubois shader in the same directory.

[Tilka]

Can you also fix the alignment?

[Tilka]

The way you previously did it was actually the Dolphin Way. It's just that some spaces were missing.

[Tilka]

lgtm

@degasus: the different API matrix multiplications differences can be bypassed abstracting the operation. The improvements to the interface I'm working on solves the problem.

[LenaWil]

Why is it not merged yet?
@Tilka approved it more than 24 hours ago.
(I'm sorry I'm so impatient)

[Tilka]

@TijmenW The thing is I don't actually know OpenGL. While we're waiting for someone to properly review this, you could rebase the two commits into one.

[LenaWil]

@Tilka Oh, ok.

To be honest, I copied the dubious shader in 262c3b1, and only edited the matrix constants and the source of the constants to avoid messing things up.
