Hey, i just found this website with a demo of a new better filtering technique. It would be great to see something like this in the game engine (in the future, since no hardware supports this yet)

I downloaded the demo and it runs at a fairly decent speed on my old toaster
BTW, there's also a demo of 16x full screen anti aliasing.

That's why i said that it might be good to see it in Blender IN THE FUTURE (and that's many years away, probably...)
But i like the name "smart texture filtering". What a smart way to make a pixelated texture look good
It was just a thought/idea/plan/gibberish anyway....
