Temporal AA sharpening

I have updated the github repo with the latest changes. It now works well both stationary and while moving. Give it a go! :cool:

Here is the current status/goals of the code.

  1. Textures should have the same sharpness as with no AA. Not less or more.

  2. Edges should have the same smoothness as with default TAA.

  3. While moving textures should have the same sharpness as with no AA. Not less or more.

  4. While moving noisy textures should have the same temporal stability as with default TAA.

  5. and 2. are pretty much done. It looks great with the default value (0.25).

  6. and 4. are working very well, but they are opposites. I can’t reduce the blur further while moving without reducing the temporal stability (jittering) in noisy textures. What I have now feels like a great middle road with unnoticeable difference on noisy textures while greatly increasing the sharpness while moving.
