Browse Source 
* First working brim ear impl, ported from SuperSlicer

* Make brim ears configurable

* Fix `Polygon::convex_points` as well as brim ear max angle

* Fix another error in `Polygon::convex_points` and `Polygon::concave_points`

* Apply brim ears to inner brims as well

* tweak hide and disable condition a bit
