Feature Request: Lens Distortion

[joshkbaker]

Hi, is there a way I can affect a layer with certain post processing effects?
I want to use the lens distortion post-processing effect on my UI elements so I can imitate a curved UI screen.

Is this possible?

It would be great in general if I could just choose any post-processing effect and have those effects only affect a certain layer in my game.

I hope you can help

Thanks
