    /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit
     * macropixel, giving effectively 16 bits 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.
     *
     * Apart 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. */

Process the WINED3DSIO_EXPP instruction in GLSL: For shader model 1.x, do the following (and honor the writemask, so use a temporary variable): dst.x = 2^(floor(src)) dst.y = src - floor(src) dst.z = 2^src (partial precision is allowed, but optional) dst.w = 1.0; For 2.0 shaders, just do this (honoring writemask and swizzle): dst = 2^src; (partial precision is allowed, but optional)

     * dst.x = 1.0;
     * if(src.x > 0.0) dst.y = src.x
     * else dst.y = 0.0.
     * if(src.x > 0.0 && src.y > 0.0) dst.z = pow(src.y, power);
     * else dst.z = 0.0;
     * dst.w = 1.0;
     * (where power = src.w clamped between -128 and 128)
     *
     * Obviously that has quite a few conditionals in it which we don't like. So the first step is this:
     * dst.x = 1.0                                  ... No further explanation needed
     * dst.y = max(src.y, 0.0);                     ... If x < 0.0, use 0.0, otherwise x. Same as the conditional
     * dst.z = x > 0.0 ? pow(max(y, 0.0), p) : 0;   ... 0 ^ power is 0, and otherwise we use y anyway
     * dst.w = 1.0.                                 ... Nothing fancy.
     *
     * So we still have one conditional in there. So do this:
     * dst.z = pow(max(0.0, src.y) * step(0.0, src.x), power);
     *
     * step(0.0, x) will return 1 if src.x > 0.0, and 0 otherwise. So if y is 0 we get pow(0.0 * 1.0, power),
     * which sets dst.z to 0. If y > 0, but x = 0.0, we get pow(y * 0.0, power), which results in 0 too.
     * if both x and y are > 0, we get pow(y * 1.0, power), as it is supposed to.
     *
     * Unfortunately pow(0.0 ^ 0.0) returns NaN on most GPUs, but lit with src.y = 0 and src.w = 0 returns
     * a non-NaN value in dst.z. What we return doesn't matter, as long as it is not NaN. Return 0, which is
     * what all Windows HW drivers and GL_ARB_vertex_program's LIT do.

Process the WINED3DSIO_SINCOS instruction in GLSL: VS 2.0 requires that specific cosine and sine constants be passed to this instruction so the hardware can handle it. But, these functions are built-in for GLSL, so we can just ignore the last 2 params.
