 *

 *
 * When GL_EXT_frag_depth is not available, which is the case on some mobile 
 * devices, we must attempt to fix this only in the vertex shader.

// Original FXAA 3.11 shader link: https://github.com/NVIDIAGameWorks/GraphicsSamples/blob/master/samples/es3-kepler/FXAA/FXAA3_11.h

// Steps used to integrate into Cesium:
// * The following defines are set:
//       #define FXAA_PC 1
//       #define FXAA_WEBGL_1 1
//       #define FXAA_GREEN_AS_LUMA 1
//       #define FXAA_EARLY_EXIT 1
//       #define FXAA_GLSL_120 1
// * All other preprocessor directives besides the FXAA_QUALITY__P* directives were removed.
// * Double underscores are invalid for preprocessor directives so replace them with a single underscore. Replace
//   /FXAA_QUALITY__P(.*)/g with /FXAA_QUALITY__P$1/.
// * There are no implicit conversions from ivec* to vec* so replace:
//       #define FxaaInt2 ivec2
//           with
//       #define FxaaInt2 vec2
// * The texture2DLod function is only available in vertex shaders so replace:
//       #define FxaaTexTop(t, p) texture2DLod(t, p, 0.0)
//       #define FxaaTexOff(t, p, o, r) texture2DLod(t, p + (o * r), 0.0)
//           with
//       #define FxaaTexTop(t, p) texture2D(t, p)
//       #define FxaaTexOff(t, p, o, r) texture2D(t, p + (o * r))
// * FXAA_QUALITY_PRESET is prepended in the javascript code. We may want to expose that setting in the future.
// * The following parameters to FxaaPixelShader are unused and can be removed:
//       fxaaConsolePosPos
//       fxaaConsoleRcpFrameOpt
//       fxaaConsoleRcpFrameOpt2
//       fxaaConsole360RcpFrameOpt2
//       fxaaConsoleEdgeSharpness
//       fxaaConsoleEdgeThreshold
//       fxaaConsoleEdgeThresholdMi
//       fxaaConsole360ConstDir

//
// Choose the quality preset.
// This needs to be compiled into the shader as it effects code.
// Best option to include multiple presets is to
// in each shader define the preset, then include this file.
//
// 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

    How is 3D data stored in a 2D megatexture?

    In this example there is only one loaded tile and it has 2x2x2 voxels (8 voxels total).
    The data is sliced by Z. The data at Z = 0 is placed in texels (0,0), (0,1), (1,0), (1,1) and
    the data at Z = 1 is placed in texels (2,0), (2,1), (3,0), (3,1).
    Note that there could be empty space in the megatexture because it's a power of two.

      0   1   2   3
    +---+---+---+---+
    |   |   |   |   | 3
    +---+---+---+---+
    |   |   |   |   | 2
    +-------+-------+
    |010|110|011|111| 1
    |--- ---|--- ---|
    |000|100|001|101| 0
    +-------+-------+

    When doing linear interpolation the megatexture needs to be sampled twice: once for
    the Z slice above the voxel coordinate and once for the slice below. The two slices
    are interpolated with fract(coord.z - 0.5). For example, a Z coordinate of 1.0 is
    halfway between two Z slices so the interpolation factor is 0.5. Below is a side view
    of the 3D voxel grid with voxel coordinates on the left side.

    2 +---+
      |001|
    1 +-z-+
      |000|
    0 +---+

    When doing nearest neighbor the megatexture only needs to be sampled once at the closest Z slice.
