7065      * two chroma(U and V) values. Each macropixel has two luminance values, one for
7066      * each single pixel it contains, and one U and one V value shared between both
7067      * pixels.
7068      *
7069      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
7070      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
7071      * take the format into account when generating the read swizzles
7072      *
7073      * Reading the Y value is straightforward - just sample the texture. The hardware
7074      * takes care of filtering in the horizontal and vertical direction.
7075      *
7076      * Reading the U and V values is harder. We have to avoid filtering horizontally,
7077      * because that would mix the U and V values of one pixel or two adjacent pixels.
7078      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7079      * regardless of the filtering setting. Vertical filtering works automatically
7080      * though - the U and V values of two rows are mixed nicely.
7081      *
7082      * Apart of avoiding filtering issues, the code has to know which value it just
7083      * read, and where it can find the other one. To determine this, it checks if
7084      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7085      *
7086      * Handling horizontal filtering of U and V values requires reading a 2nd pair
7087      * of pixels, extracting U and V and mixing them. This is not implemented yet.
7088      *
7089      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7090      * with width / 2. This way one read gives all 3 values, finding U and V is easy
7091      * in an unfiltered situation. Finding the luminance on the other hand requires
7092      * finding out if it is an odd or even pixel. The real drawback of this approach
7093      * is filtering. This would have to be emulated completely in the shader, reading
7094      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7095      * vertically. Beyond that it would require adjustments to the texture handling
7096      * code to deal with the width scaling
