Added CAS sharpening to SMAA antialiasing.

[Muzz]

Just to explain motivation here.

I'm not a fan of the ghosting of TAA, but i think most people would say it looks best in static screenshots because of the sharpening inside of it.

So i wanted something that had that crispy look, but more configurable, so I wrote an implementation based on https://gpuopen.com/fidelityfx-cas/

Currently it's always on when SMAA is active, so you may want to throw in a switch for it.

give it a shot, i think it looks quite nice.

examples:

NO AA

TAA

SMAA with CAS

Not sure correct way to push a modified .flax shader because of the gitlab LFS btw, so i just pushed with no verify. I know it's a generated file so i think that's ok?

Did you change something between the first two and the last screenshot? the dark cracks on the rock texture are significantly darker on the last image.

That's just the results of a different sharpening algorithm. But you are welcome to test and check my working.

if u need to submit modified .flax use the zip file for it

That's fine I'll update shader binary, shader source is only needed for this.
