7081      *
7082      * Reading the U and V values is harder. We have to avoid filtering horizontally,
7083      * because that would mix the U and V values of one pixel or two adjacent pixels.
7084      * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
7085      * regardless of the filtering setting. Vertical filtering works automatically
7086      * though - the U and V values of two rows are mixed nicely.
7087      *
7088      * Apart of avoiding filtering issues, the code has to know which value it just
7089      * read, and where it can find the other one. To determine this, it checks if
7090      * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
7091      *
7092      * Handling horizontal filtering of U and V values requires reading a 2nd pair
7093      * of pixels, extracting U and V and mixing them. This is not implemented yet.
7094      *
7095      * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
7096      * with width / 2. This way one read gives all 3 values, finding U and V is easy

7098      * finding out if it is an odd or even pixel. The real drawback of this approach
7099      * is filtering. This would have to be emulated completely in the shader, reading
7100      * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
7101      * vertically. Beyond that it would require adjustments to the texture handling
