c3f1eb9b06 [test] remove two conditionals because these cases now also succeed, 
either after selecting IP differently, or after rescale/rounding (or both)

606cb236af [buffer][test] update expected values after change to rounding in rescaling, 
and increased the tolerance.
Largest difference was 1.3e-05% (it100 deflate, 9087m2) and results are checked visually

5fa509783d [buffer][test] Alter the expected result and tolerance for one MLs case. 
Increase the tolerance two times. With MSVC and MinGW the results are so
different that the currently used tolerance is too small.

452f092e8e [buffer][test] use a rescale policy calculated over the output, instead 
of over the input. This shows problems in the newly added test, and also
invalidates one other testcase.

Both problems (self-intersections) should be solved later

6158064410 [buffer] performance optimization: set the center point for buffers around 
(multi)points, calculate min/max radius
and (when checking turn w.r.t. piece) check turn distance to center,
in most cases leave early

Including unit test. For multipoint_b_500k this increases performance with
a factor 6 (340 seconds -> 55 seconds)

Note, this is done for buffers around points but could be done for other
geometry types too (using e.g. centroid)

d7a25934c3 [buffer][test] exclude case q2 for new approach. 
As mailed to Adam: "But that is not related to the new method
- it is only by chance that it now fails and earlier succeeded.
This is a known problem which I still need to solve:
if two IP's are exactly on top of each other,
where a u/u turn is also involved, it can fail
(depending on sort-order, so depending on configuration)."

Thanks to Menelaos for spotting and Adam for the calculation

fc2652323b [buffer] refactor analysis of piece into shorter and slightly more efficient (few %) code. 
It is now one function. In later commits we will extend this by checking helper

9a9e16f936 [buffer] major fix: we now create concave helper-pieces differently 
In the past there was one with a straight line going from one piece to the next.
Now there are two, going from one piece to the point on the geometry, and the
second going from the point on the geomety to the next piece.
They are now zero-volume.
They fix:
1) crossings of sides with flat-ends (unit-test cases curve, field_sprayer, bend_near_start)
2) joins with limited number of points (unit-test cases concave_b_rough, italy_part, nl_part)
3) joins with large distances
4) many self-intersections on remaining aimes-cases

a46e2603d8 [buffer][fix] In rare cases an extra ring was traversed and created. Fixed, that ring is 
discarded now. This fixes behaviour of assign_parents with positive-rings in positive-rings (when
check_for_orientation is true; normally (for overlay) it is false)

It also reverses a negative-only ring so fixes a linestring_buffer testcase.

For multi-polygon it fixes new testcase rt_u2 found by recursive-polygon-buffer test

e1fc427e30 [buffer][fix] Mark points in buffered areas as not startable instead of discarding them 
Within can have in rare cases a rounding issue. We don't discard this
point, so it can be used to continue started rings in traversal. But
will never start a new ring from this type of points.
