3434      * pixels.

3442      *
3443      * Reading the U and V values is harder. We have to avoid filtering horizontally,
3444      * because that would mix the U and V values of one pixel or two adjacent pixels.
3445      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
3446      * regardless of the filtering setting. Vertical filtering works automatically
3447      * though - the U and V values of two rows are mixed nicely.
3448      *
3449      * Appart of avoiding filtering issues, the code has to know which value it just
3450      * read, and where it can find the other one. To determine this, it checks if
3451      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
3452      *
3453      * Handling horizontal filtering of U and V values requires reading a 2nd pair
3454      * of pixels, extracting U and V and mixing them. This is not implemented yet.
3455      *
3456      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,

3458      * in an unfiltered situation. Finding the luminance on the other hand requires
3459      * finding out if it is an odd or even pixel. The real drawback of this approach
3460      * is filtering. This would have to be emulated completely in the shader, reading
3461      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
3462      * vertically. Beyond that it would require adjustments to the texture handling
