Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
- could crash if triangulate attempted to create an existing face.
- tagging edges to rotate was unreliable, don't do this anymore.
now check if edge is in the array passed to the beauty function.
Project the triangle pair into 2d coords before measuring.

note: I committed this r54403 but it caused eternal looping so I reverted for 2.66 release.
ran extensive tests and its not giving problems so re-applying this improvement.
The way beauty fill was working was too fragile and prone to eternal loops,
Solution used is to is to store previous states and ensure edges don't get rotated back into those.
Also added an optimization to avoid testing the same edge rotation many times - using edge tags to only re-test edge rotations around areas that have been modified.
