[buffer] fix adding piece for side with a range, the intermediate range points were
not added (there is not yet a strategy doing this). Share functionality for adding
a range
[buffer] helper_points (formerly called helper_segments) are now optional
and we rescale/finish the piece on the fly and not in a separate call
[buffer] fix cases where intersection point falls between robust piece
and non-robust original. We now check robust representions of originals
where this cannot happen
This fixes rt_u9
This obsoletes turn_in_input
[buffer] add comments
[buffer][test] added new failing testcase rt_u10
[test][within] Add tests for spherical point in poly.
[within] Fix winding strategy MSVC compilation error. Remove the typename keyword from a type definition without dependent type.
