7110      *
7111      * Reading the U and V values is harder. We have to avoid filtering horizontally,
7112      * because that would mix the U and V values of one pixel or two adjacent pixels.
7113      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7114      * regardless of the filtering setting. Vertical filtering works automatically
7115      * though - the U and V values of two rows are mixed nicely.
7116      *
7117      * Apart of avoiding filtering issues, the code has to know which value it just
7118      * read, and where it can find the other one. To determine this, it checks if
7119      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7120      *
7121      * Handling horizontal filtering of U and V values requires reading a 2nd pair
7122      * of pixels, extracting U and V and mixing them. This is not implemented yet.
7123      *
7124      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7125      * with width / 2. This way one read gives all 3 values, finding U and V is easy
7126      * in an unfiltered situation. Finding the luminance on the other hand requires
7127      * finding out if it is an odd or even pixel. The real drawback of this approach
7128      * is filtering. This would have to be emulated completely in the shader, reading
7129      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7130      * vertically. Beyond that it would require adjustments to the texture handling
