Yeah I did. It is worthless. What it does it applies an radial mask to a rectangular texture. But you can do the same and even better by adding a radial alpha layer yourself in the TGA file.
It only makes sense if you want to apply it to textures that have no radial mask by itself.
Where it _can_ be cool is actionbutton and aura icon textures. (You could make them all radial)
