Describe the bug
When slicing the stl the slicer stops at "Generating perimeters: layer".
Everything is still usable until "cancel" button is pressed, it freezes.

Problem is only with my profile because it contains "Reverse on odd".
As soon as the option is deactivated everything works again.

This might be one of those edge cases since other files are fine.

The problem was on the bridge detector, iterating on too many angles.
I've fixed the bug and used the opportunity to improve the pruning algo.
