What a crappy compiler but I guess it's within the spec technically since it calls the sqrt function. We could work out the actual value by hand and leave a comment as to what was used to calculate it. That way we can keep this as a constant and avoid a sqrt() operation per fragment.

right. sounds good. i'll change that.
