I would that, not necessarily invent, but create a unique AA technique, that not only remove aliasing, well as all make, but also have a supreme quality, upper peformance, color enhancer and sharp image function in other words:
A hybrid smart technique, using the best there is out there, in other techniques like: FXAA/SMAA/CMAA/DLAA and others you may know.
Purpose: free use for game developers & game modding.
I do not have a key idea for it, but can be based on the descriptions.
-Sorry, I'm just dreaming a little louder.
