Revert "offset angle check edge in common"

This reverts commit d2eb581ebc8f8009e80cccccd74d5b341ef5bd5b.

Reason for revert: broke Google3 MSAN run of dm

Original change's description:
> offset angle check edge in common
> 
> When curves cross, their intersection points may be nearby, but not exactly the same.
> Sort the angles formed by the crossing curves when all angles don't have the same
> origin.
> 
> This sets up the framework to solve test case that currently fail (e.g., joel6) but
> does not fix all related test cases (e.g., joel9).
> 
> All older existing test cases, including extended tests, pass.
> 
> Rework the test framework to better report when tests expected to produce failing
> results now pass.
> 
> Add new point and vector operations to support offset angles.
