GPU Open used to include a project called "AOFX", hosted at https://github.com/GPUOpen-Effects/AOFX/ however, all trace of AOFX seems to have been purged from the internet. It's like it never existed!

I'm using this library in our product, and the fact that it's been "disappeared" kind of scares me. Why did AMD delete it? Does it violate patents or something like that? Am I putting myself at risk by continuing to use it?

Thanks.
