Improve normal calculations
...
Soooo. It turns out that the bunch of smallish (~4-5% of runtime)
loads associated with Len(), Unit(), Rotated(), and so on... Were
actually more like 15% or more of computational effort. I first
figured this out by creating:
func (u Vec) Normal(v Vec) Vec
which gives you a vector normal to u->v. That consumed a lot
of CPU time, and was followed by .Unit().Scaled(imd.thickness / 2),
which consumed a bit more CPU time.
After some poking, and in the interests of avoiding UI cruft,
the final selection is
func (u Vec) Normal() Vec
This returns the vector rotated 90 degrees, which turns out to
be the most common problem.
