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

* dst.z = pow(max(0.0, src.y) * step(0.0, src.x), power);

* 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
