Calculates a distance vector.

The following code fragment shows the operations performed:
dest.x = 1; dest.y = src0.y * src1.y; dest.z = src0.z; dest.w = src1.w;
The first source operand (src0) is assumed to be the vector (ignored, d*d, d*d, ignored) and the second source operand (src1) is assumed to be the vector (ignored, 1/d, ignored, 1/d). The destination (dest) is the result vector (1, d, d*d, 1/d).
