/* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
* giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
* two chroma(U and V) values. Each macropixel has two luminance values, one for
* each single pixel it contains, and one U and one V value shared between both
* pixels.
*
* The data is loaded into an A8L8 texture. With YUY2, the luminance component
* contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
* take the format into account when generating the read swizzles
*
* Reading the Y value is straightforward - just sample the texture. The hardware
* takes care of filtering in the horizontal and vertical direction.
*
* Reading the U and V values is harder. We have to avoid filtering horizontally,
* because that would mix the U and V values of one pixel or two adjacent pixels.
* Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
* regardless of the filtering setting. Vertical filtering works automatically
* though - the U and V values of two rows are mixed nicely.
*
* Appart of avoiding filtering issues, the code has to know which value it just
* read, and where it can find the other one. To determine this, it checks if
* it sampled an even or odd pixel, and shifts the 2nd read accordingly.
*
* Handling horizontal filtering of U and V values requires reading a 2nd pair
* of pixels, extracting U and V and mixing them. This is not implemented yet.
*
* An alternative implementation idea is to load the texture as A8R8G8B8 texture,
* with width / 2. This way one read gives all 3 values, finding U and V is easy
* in an unfiltered situation. Finding the luminance on the other hand requires
* finding out if it is an odd or even pixel. The real drawback of this approach
* is filtering. This would have to be emulated completely in the shader, reading
* up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
* vertically. Beyond that it would require adjustments to the texture handling
* code to deal with the width scaling
