    /* The sdk specifies the instruction like this
     * 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.
