Perform FXAA antialiasing on the current framebuffer.
Call Execute() to run a FXAA antialiasing pass on the current OpenGL framebuffer. See method documentation for tunable parameters.
Based on the following implementation and description:
Whitepaper: http://developer.download.nvidia.com/assets/gamedev/files/sdk/11/FXAA_WhitePaper.pdf
Sample implementation: https://github.com/NVIDIAGameWorks/GraphicsSamples/blob/master/samples/es3-kepler/FXAA/FXAA3_11.h
TODO there are currently some "banding" artifacts on some edges, particularly single pixel lines. These seem to be caused by using a linear RGB input, rather than a gamma-correct sRGB input. Future work should combine this pass with a gamma correction pass to correct this. Bonus points for precomputing luminosity into the sRGB's alpha channel to save cycles in the FXAA shader!
