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