* Fix#12469 - crash caused by bridge expansion.
Handle a very rare case in which the algorithm picks a wrong
polygon for expansion seed.
(cherry picked from commit 5f843cc93470c96483abcbd47cf8ee5fe38dffe2)
* SPE-2698: Fix crash during regions expansion.

According to https://eigen.tuxfamily.org/dox/TopicPitfalls.html one
should just avoid using `auto` as the type of an Eigen expression.
This PR fixes most of them I could found in the project. There might be
cases that I missed, and I might update those later if I noticed.
This should prevent issues like #7741 and hopefully fix some mysterious
crashes happened inside Eigen calls.
* SPE-1950: Reimplement algorithm for filtering vibrating extractions inside the ensuring infill to make it less computation complex.
