6997      * two chroma(U and V) values. Each macropixel has two luminance values, one for
6998      * each single pixel it contains, and one U and one V value shared between both
6999      * pixels.
7000      *
7001      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
7002      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
7003      * take the format into account when generating the read swizzles
7004      *
7005      * Reading the Y value is straightforward - just sample the texture. The hardware
7006      * takes care of filtering in the horizontal and vertical direction.
7007      *
7008      * Reading the U and V values is harder. We have to avoid filtering horizontally,
7009      * because that would mix the U and V values of one pixel or two adjacent pixels.
7010      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7011      * regardless of the filtering setting. Vertical filtering works automatically
7012      * though - the U and V values of two rows are mixed nicely.
7013      *
7014      * Appart of avoiding filtering issues, the code has to know which value it just
7015      * read, and where it can find the other one. To determine this, it checks if
7016      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7017      *
7018      * Handling horizontal filtering of U and V values requires reading a 2nd pair
7019      * of pixels, extracting U and V and mixing them. This is not implemented yet.
7020      *
7021      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7022      * with width / 2. This way one read gives all 3 values, finding U and V is easy
7023      * in an unfiltered situation. Finding the luminance on the other hand requires
7024      * finding out if it is an odd or even pixel. The real drawback of this approach
7025      * is filtering. This would have to be emulated completely in the shader, reading
7026      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7027      * vertically. Beyond that it would require adjustments to the texture handling
7028      * code to deal with the width scaling
