7086 * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
7087 * take the format into account when generating the read swizzles
7089 * Reading the Y value is straightforward - just sample the texture. The hardware
7090 * takes care of filtering in the horizontal and vertical direction.
7092 * Reading the U and V values is harder. We have to avoid filtering horizontally,
7093 * because that would mix the U and V values of one pixel or two adjacent pixels.
7094 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7095 * regardless of the filtering setting. Vertical filtering works automatically
7096 * though - the U and V values of two rows are mixed nicely.
7098 * Apart of avoiding filtering issues, the code has to know which value it just
7099 * read, and where it can find the other one. To determine this, it checks if
7100 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7102 * Handling horizontal filtering of U and V values requires reading a 2nd pair

7105 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7106 * with width / 2. This way one read gives all 3 values, finding U and V is easy
7107 * in an unfiltered situation. Finding the luminance on the other hand requires
7108 * finding out if it is an odd or even pixel. The real drawback of this approach
7109 * is filtering. This would have to be emulated completely in the shader, reading
7110 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7111 * vertically. Beyond that it would require adjustments to the texture handling
7112 * code to deal with the width scaling
