Changing AA settings at runtime

Hi Freya, thanks for the amazing package :D

I'm building an application that's kind of sandboxy and I like the idea of allowing the user to turn the AA on and off, but from my quick inspection it didn't seem like an easy task at runtime, since you need to recompile the shaders in Editor in order for the changes to apply.

Would it be possible to do this at runtime (and in a build), or is this kind of thing reserved to Editor?
