6472     /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
6473      * giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
6474      * two chroma(U and V) values. Each macropixel has two luminance values, one for
6475      * each single pixel it contains, and one U and one V value shared between both
6476      * pixels.
6477      *
6478      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
6479      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
6480      * take the format into account when generating the read swizzles
6481      *
6482      * Reading the Y value is straightforward - just sample the texture. The hardware
6483      * takes care of filtering in the horizontal and vertical direction.
6484      *
6485      * Reading the U and V values is harder. We have to avoid filtering horizontally,
6486      * because that would mix the U and V values of one pixel or two adjacent pixels.
6487      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
6488      * regardless of the filtering setting. Vertical filtering works automatically
6489      * though - the U and V values of two rows are mixed nicely.
6490      *
6491      * Appart of avoiding filtering issues, the code has to know which value it just
6492      * read, and where it can find the other one. To determine this, it checks if
6493      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
6494      *
6495      * Handling horizontal filtering of U and V values requires reading a 2nd pair
6496      * of pixels, extracting U and V and mixing them. This is not implemented yet.
6497      *
6498      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
6499      * with width / 2. This way one read gives all 3 values, finding U and V is easy
6500      * in an unfiltered situation. Finding the luminance on the other hand requires
6501      * finding out if it is an odd or even pixel. The real drawback of this approach
6502      * is filtering. This would have to be emulated completely in the shader, reading
6503      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
6504      * vertically. Beyond that it would require adjustments to the texture handling
6505      * code to deal with the width scaling
