+(1.)
+In the shader source, setup defines for the desired configuration.
+When providing multiple shaders (for different presets),
+simply setup the defines differently in multiple files.
+Example,
+
+ #define FXAA_PC 1
+ #define FXAA_HLSL_5 1
+ #define FXAA_QUALITY__PRESET 12
+
+Or,
+
+ #define FXAA_360 1
+
+Or,
+
+ #define FXAA_PS3 1
+
+Etc.
+
+(2.)
+Then include this file,
+
+ #include "Fxaa3_11.h"
+
+(3.)
+Then call the FXAA pixel shader from within your desired shader.
+Look at the FXAA Quality FxaaPixelShader() for docs on inputs.
+As for FXAA 3.11 all inputs for all shaders are the same
+to enable easy porting between platforms.
+
+ return FxaaPixelShader(...);
+
+(4.)
+Insure pass prior to FXAA outputs RGBL (see next section).
+Or use,
+
+ #define FXAA_GREEN_AS_LUMA 1
+
+(5.)
+Setup engine to provide the following constants
+which are used in the FxaaPixelShader() inputs,
+
+ FxaaFloat2 fxaaQualityRcpFrame,
+ FxaaFloat4 fxaaConsoleRcpFrameOpt,
+ FxaaFloat4 fxaaConsoleRcpFrameOpt2,
+ FxaaFloat4 fxaaConsole360RcpFrameOpt2,
+ FxaaFloat fxaaQualitySubpix,
+ FxaaFloat fxaaQualityEdgeThreshold,
+ FxaaFloat fxaaQualityEdgeThresholdMin,
+ FxaaFloat fxaaConsoleEdgeSharpness,
+ FxaaFloat fxaaConsoleEdgeThreshold,
+ FxaaFloat fxaaConsoleEdgeThresholdMin,
+ FxaaFloat4 fxaaConsole360ConstDir
+
+Look at the FXAA Quality FxaaPixelShader() for docs on inputs.
+
+(6.)
+Have FXAA vertex shader run as a full screen triangle,
+and output "pos" and "fxaaConsolePosPos"
+such that inputs in the pixel shader provide,
+
+ // {xy} = center of pixel
+ FxaaFloat2 pos,
+
+ // {xy__} = upper left of pixel
+ // {__zw} = lower right of pixel
+ FxaaFloat4 fxaaConsolePosPos,
+
+(7.)
+Insure the texture sampler(s) used by FXAA are set to bilinear filtering.
+
+
+------------------------------------------------------------------------------
+ INTEGRATION - RGBL AND COLORSPACE
+------------------------------------------------------------------------------
+FXAA3 requires RGBL as input unless the following is set,
+
+ #define FXAA_GREEN_AS_LUMA 1
+
+In which case the engine uses green in place of luma,
+and requires RGB input is in a non-linear colorspace.
+
+RGB should be LDR (low dynamic range).
+Specifically do FXAA after tonemapping.
+
+RGB data as returned by a texture fetch can be non-linear,
+or linear when FXAA_GREEN_AS_LUMA is not set.
+Note an "sRGB format" texture counts as linear,
+because the result of a texture fetch is linear data.
+Regular "RGBA8" textures in the sRGB colorspace are non-linear.
+
+If FXAA_GREEN_AS_LUMA is not set,
+luma must be stored in the alpha channel prior to running FXAA.
+This luma should be in a perceptual space (could be gamma 2.0).
+Example pass before FXAA where output is gamma 2.0 encoded,
+
+ color.rgb = ToneMap(color.rgb); // linear color output
+ color.rgb = sqrt(color.rgb); // gamma 2.0 color output
+ return color;
+
+To use FXAA,
+
+ color.rgb = ToneMap(color.rgb); // linear color output
+ color.rgb = sqrt(color.rgb); // gamma 2.0 color output
+ color.a = dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114)); // compute luma
+ return color;
+
+Another example where output is linear encoded,
+say for instance writing to an sRGB formated render target,
+where the render target does the conversion back to sRGB after blending,
+
+ color.rgb = ToneMap(color.rgb); // linear color output
+ return color;
+
+To use FXAA,
+
+ color.rgb = ToneMap(color.rgb); // linear color output
+ color.a = sqrt(dot(color.rgb, FxaaFloat3(0.299, 0.587, 0.114))); // compute luma
+ return color;
+
+Getting luma correct is required for the algorithm to work correctly.
+
+
+------------------------------------------------------------------------------
+ BEING LINEARLY CORRECT?
+------------------------------------------------------------------------------
+Applying FXAA to a framebuffer with linear RGB color will look worse.
+This is very counter intuitive, but happends to be true in this case.
+The reason is because dithering artifacts will be more visiable
+in a linear colorspace.
+
+
+------------------------------------------------------------------------------
+ COMPLEX INTEGRATION
+------------------------------------------------------------------------------
+Q. What if the engine is blending into RGB before wanting to run FXAA?
+
+A. In the last opaque pass prior to FXAA,
+ have the pass write out luma into alpha.
+ Then blend into RGB only.
+ FXAA should be able to run ok
+ assuming the blending pass did not any add aliasing.
+ This should be the common case for particles and common blending passes.
+
+A. Or use FXAA_GREEN_AS_LUMA.

+ FXAA3 CONSOLE - OPTIMIZED PS3 PIXEL SHADER (WITH EARLY EXIT)
+
+==============================================================================
+The code mostly matches the assembly.
+I have a feeling that 14 cycles is possible, but was not able to get there.
+Might have to increase register count to get full performance.
+Note this shader does not use perspective interpolation.
+
+Use the following cgc options,
+
+ --fenable-bx2 --fastmath --fastprecision --nofloatbindings
+
+Use of FXAA_GREEN_AS_LUMA currently adds a cycle (16 clks).
+Will look at fixing this for FXAA 3.12.
