//
// OPTIONS
// -----------------------------------------------------------------------
// 10 to 15 - default medium dither (10=fastest, 15=highest quality)
// 20 to 29 - less dither, more expensive (20=fastest, 29=highest quality)
// 39 - no dither, very expensive
//
// NOTES
// -----------------------------------------------------------------------
// 12 = slightly faster then FXAA 3.9 and higher edge quality (default)
// 13 = about same speed as FXAA 3.9 and better than 12
// 23 = closest to FXAA 3.9 visually and performance wise
// _ = the lowest digit is directly related to performance
// _ = the highest digit is directly related to style
