We don't have any immediate plans to re-implement FXAA in the OpenGL renderer as we are working to avoid doing any post-processing at all. The post-processing pass required for FXAA can be a killer on mobile devices.

Moving the milestone as this definitely won't be added for 4.0. We can consider adding it in later releases as we expose more performance trade-offs to users (i.e. we could make the post processing pass optional)
