Changes between Initial Version and Version 1 of Ticket #2039, comment 12

initial	v1
3	3	In any case, Anchoring doesn't need a normalized orthogonal, and most other code doesn't need it either (only the direction of the vector is important). So I worked out the cross product, and removed the normalize.
4	4
5		This brings the anchor calculation from 1.05 us to 0.94 us according to my profiling, ~~but I don't know how much the profiling overhead is with these tiny times~~.
	5	This brings the anchor calculation from 1.05 us to 0.94 us according to my profiling, with a profiling overhead that seems to be around 0.34 us. So that gives a speedup of around 15% when leaving out the profiling overhead.

7	7	It certainly break terrain boundary rendering, and probably some water related stuff too, so it's not for inclusion, but a method could be added to calculate an unnormalized orthogonal to speed up anchoring calculation.
