25 * D3D shader asm has swizzles on source parameters, and write masks for
26 * destination parameters. GLSL uses swizzles for both. The result of this is
27 * that for example "mov dst.xw, src.zyxw" becomes "dst.xw = src.zw" in GLSL.
28 * Ie, to generate a proper GLSL source swizzle, we need to take the D3D write
29 * mask for the destination parameter into account.

4848 * dst.x = 1.0 ... No further explanation needed

4858 * if both x and y are > 0, we get pow(y * 1.0, power), as it is supposed to.
4860 * Unfortunately pow(0.0 ^ 0.0) returns NaN on most GPUs, but lit with src.y = 0 and src.w = 0 returns
4861 * a non-NaN value in dst.z. What we return doesn't matter, as long as it is not NaN. Return 0, which is

12547 * luminance values, one for each single pixel it contains, and one U and
12548 * one V value shared between both pixels.
12550 * The data is loaded into an A8L8 texture. With YUY2, the luminance
12551 * component contains the luminance and alpha the chroma. With UYVY it is
12552 * vice versa. Thus take the format into account when generating the read
12555 * Reading the Y value is straightforward - just sample the texture. The
12556 * hardware takes care of filtering in the horizontal and vertical
12559 * Reading the U and V values is harder. We have to avoid filtering
12560 * horizontally, because that would mix the U and V values of one pixel or
12561 * two adjacent pixels. Thus floor the texture coordinate and add 0.5 to
12562 * get an unfiltered read, regardless of the filtering setting. Vertical
12563 * filtering works automatically though - the U and V values of two rows
12564 * are mixed nicely.
12566 * Apart of avoiding filtering issues, the code has to know which value it
12567 * just read, and where it can find the other one. To determine this, it
12568 * checks if it sampled an even or odd pixel, and shifts the 2nd read
12571 * Handling horizontal filtering of U and V values requires reading a 2nd
12572 * pair of pixels, extracting U and V and mixing them. This is not
12575 * An alternative implementation idea is to load the texture as A8R8G8B8
12576 * texture, with width / 2. This way one read gives all 3 values, finding
12577 * U and V is easy in an unfiltered situation. Finding the luminance on
12578 * the other hand requires finding out if it is an odd or even pixel. The
12579 * real drawback of this approach is filtering. This would have to be
12580 * emulated completely in the shader, reading up two 2 packed pixels in up
12581 * to 2 rows and interpolating both horizontally and vertically. Beyond
12582 * that it would require adjustments to the texture handling code to deal
12583 * with the width scaling. */
