// For those using non-linear color,

// So with this enabled, no need to pack luma in alpha.

// This will turn off AA on anything which lacks some amount of green.
// Pure red and blue or combination of only R and B, will get no AA.

// Might want to lower the settings for both,

// fxaaQualityEdgeThresholdMin
// In order to insure AA does not get turned off on colors
