6931     /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
6932      * giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
6933      * two chroma(U and V) values. Each macropixel has two luminance values, one for
6934      * each single pixel it contains, and one U and one V value shared between both
6935      * pixels.
6936      *
6937      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
6938      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
6939      * take the format into account when generating the read swizzles
6940      *
6941      * Reading the Y value is straightforward - just sample the texture. The hardware
6942      * takes care of filtering in the horizontal and vertical direction.
6943      *
6944      * Reading the U and V values is harder. We have to avoid filtering horizontally,
6945      * because that would mix the U and V values of one pixel or two adjacent pixels.
6946      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
6947      * regardless of the filtering setting. Vertical filtering works automatically
6948      * though - the U and V values of two rows are mixed nicely.
6949      *
6950      * Appart of avoiding filtering issues, the code has to know which value it just
6951      * read, and where it can find the other one. To determine this, it checks if
6952      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
6953      *
6954      * Handling horizontal filtering of U and V values requires reading a 2nd pair
6955      * of pixels, extracting U and V and mixing them. This is not implemented yet.
6956      *
6957      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
6958      * with width / 2. This way one read gives all 3 values, finding U and V is easy
6959      * in an unfiltered situation. Finding the luminance on the other hand requires
6960      * finding out if it is an odd or even pixel. The real drawback of this approach
6961      * is filtering. This would have to be emulated completely in the shader, reading
6962      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
6963      * vertically. Beyond that it would require adjustments to the texture handling
6964      * code to deal with the width scaling
