3602      * though - the U and V values of two rows are mixed nicely.
3603      *
3604      * Appart of avoiding filtering issues, the code has to know which value it just
3605      * read, and where it can find the other one. To determine this, it checks if
3606      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
3607      *
3608      * Handling horizontal filtering of U and V values requires reading a 2nd pair
3609      * of pixels, extracting U and V and mixing them. This is not implemented yet.
3610      *
3611      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
3612      * with width / 2. This way one read gives all 3 values, finding U and V is easy
3613      * in an unfiltered situation. Finding the luminance on the other hand requires
3614      * finding out if it is an odd or even pixel. The real drawback of this approach
3615      * is filtering. This would have to be emulated completely in the shader, reading
3616      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
3617      * vertically. Beyond that it would require adjustments to the texture handling
3618      * code to deal with the width scaling
