Description

Fixes #10235 but blocked by #11915
Fix #12817

The Maximum resolution and Maximum deviation constants were exposed as config options, so users can now tweak their values.

TODO list:

Merge this PR first: #11915. It needs to be able to set a proper range (min/max) for new options.
Come up with the proper descriptions for the new options.
Determine the appropriate ranges for the new options.

About ranges. I propose these values:

Maximum Resolution: [0.005, 0.5] (0.5 is the current value of the constant)
Maximum Deviation: [0.005, 0.025] (0.025 is the current value of the constant)

Screenshots

Classic

Arachne (default)

As you can see, the slicing result has many more artifacts than the classic algorithm.

Arachne (minimal maximum resolution and deviation)

Almost all the artefacts are gone, but there's still room for improvement.

Arachne (maximum resolution and deviation twice higher than default)
