3718      * pixels.
3719      *
3720      * The data is loaded into an A8L8 texture. With YUY2, the luminance component
3721      * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
3722      * take the format into account when generating the read swizzles
3723      *
3724      * Reading the Y value is straightforward - just sample the texture. The hardware
3725      * takes care of filtering in the horizontal and vertical direction.
3726      *
3727      * Reading the U and V values is harder. We have to avoid filtering horizontally,
3728      * because that would mix the U and V values of one pixel or two adjacent pixels.
3729      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
3730      * regardless of the filtering setting. Vertical filtering works automatically
3731      * though - the U and V values of two rows are mixed nicely.
3732      *
3733      * Appart of avoiding filtering issues, the code has to know which value it just
3734      * read, and where it can find the other one. To determine this, it checks if
3735      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
3736      *
3737      * Handling horizontal filtering of U and V values requires reading a 2nd pair
3738      * of pixels, extracting U and V and mixing them. This is not implemented yet.
3739      *
3740      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
3741      * with width / 2. This way one read gives all 3 values, finding U and V is easy
3742      * in an unfiltered situation. Finding the luminance on the other hand requires
3743      * finding out if it is an odd or even pixel. The real drawback of this approach
3744      * is filtering. This would have to be emulated completely in the shader, reading
3745      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
3746      * vertically. Beyond that it would require adjustments to the texture handling
