7103 * two chroma(U and V) values. Each macropixel has two luminance values, one for
7104 * each single pixel it contains, and one U and one V value shared between both
7107 * The data is loaded into an A8L8 texture. With YUY2, the luminance component
7108 * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
7109 * take the format into account when generating the read swizzles
7111 * Reading the Y value is straightforward - just sample the texture. The hardware
7112 * takes care of filtering in the horizontal and vertical direction.
7114 * Reading the U and V values is harder. We have to avoid filtering horizontally,
7115 * because that would mix the U and V values of one pixel or two adjacent pixels.
7116 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7117 * regardless of the filtering setting. Vertical filtering works automatically
7118 * though - the U and V values of two rows are mixed nicely.
7120 * Apart of avoiding filtering issues, the code has to know which value it just
7121 * read, and where it can find the other one. To determine this, it checks if
7122 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7124 * Handling horizontal filtering of U and V values requires reading a 2nd pair
7125 * of pixels, extracting U and V and mixing them. This is not implemented yet.
7127 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7128 * with width / 2. This way one read gives all 3 values, finding U and V is easy
7129 * in an unfiltered situation. Finding the luminance on the other hand requires
7130 * finding out if it is an odd or even pixel. The real drawback of this approach
7131 * is filtering. This would have to be emulated completely in the shader, reading
7132 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7133 * vertically. Beyond that it would require adjustments to the texture handling
7134 * code to deal with the width scaling
