FXAA Fast Approximate Anti-Aliasing

FXAA is a popular post-process anti-aliasing technique created by Timothy Lottes. While mostly used in deferred rendering pipelines that lack the ability to use hardware MSAA, it can also be used in combination with hardware anti-aliasing to smooth out hard edges missed by MSAA, such as inside polygons. Add the FXAA.cs component to your camera, no configuration required.
