6903     /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
6904      * giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
6905      * two chroma(U and V) values. Each macropixel has two luminance values, one for
6906      * each single pixel it contains, and one U and one V value shared between both
6907      * pixels.
6908      *
6909      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
6910      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
6911      * take the format into account when generating the read swizzles
6912      *
6913      * Reading the Y value is straightforward - just sample the texture. The hardware
6914      * takes care of filtering in the horizontal and vertical direction.
6915      *
6916      * Reading the U and V values is harder. We have to avoid filtering horizontally,
6917      * because that would mix the U and V values of one pixel or two adjacent pixels.
6918      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
6919      * regardless of the filtering setting. Vertical filtering works automatically
6920      * though - the U and V values of two rows are mixed nicely.
6921      *
6922      * Appart of avoiding filtering issues, the code has to know which value it just
6923      * read, and where it can find the other one. To determine this, it checks if
6924      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
6925      *
6926      * Handling horizontal filtering of U and V values requires reading a 2nd pair
6927      * of pixels, extracting U and V and mixing them. This is not implemented yet.
6928      *
6929      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
6930      * with width / 2. This way one read gives all 3 values, finding U and V is easy
6931      * in an unfiltered situation. Finding the luminance on the other hand requires
6932      * finding out if it is an odd or even pixel. The real drawback of this approach
6933      * is filtering. This would have to be emulated completely in the shader, reading
6934      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
6935      * vertically. Beyond that it would require adjustments to the texture handling
6936      * code to deal with the width scaling
