Browse source 
* Initial port of the new ensure vertical thickness algorithm from PrusaSlicer.

Based on prusa3d/PrusaSlicer@1a0d8f5130

* Remove code related to "Detect narrow internal solid infill" as it's handled by the new ensuring code

* Support different internal solid infill pattern

* Ignore removed options
