7096 * Reading the Y value is straightforward - just sample the texture. The hardware
7097 * takes care of filtering in the horizontal and vertical direction.
7099 * Reading the U and V values is harder. We have to avoid filtering horizontally,
7100 * because that would mix the U and V values of one pixel or two adjacent pixels.
7101 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7102 * regardless of the filtering setting. Vertical filtering works automatically
7103 * though - the U and V values of two rows are mixed nicely.
7105 * Apart of avoiding filtering issues, the code has to know which value it just
7106 * read, and where it can find the other one. To determine this, it checks if
7107 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7109 * Handling horizontal filtering of U and V values requires reading a 2nd pair

7112 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7113 * with width / 2. This way one read gives all 3 values, finding U and V is easy
7114 * in an unfiltered situation. Finding the luminance on the other hand requires
7115 * finding out if it is an odd or even pixel. The real drawback of this approach
7116 * is filtering. This would have to be emulated completely in the shader, reading
7117 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7118 * vertically. Beyond that it would require adjustments to the texture handling
7119 * code to deal with the width scaling
