This PR unlocks and configure overhang offset support threshold in addition to angle threshold. Actually angle threshold has no intrinsic meaning, because it's offset which affects overhangs quality. Angle that could be printed without support is function of layer width and height.

This option sets percent of not supported external perimeter width triggering support

Width 0.62, layer 0.32, offset threshold 50%

Width 0.62, layer 0.32, offset threshold 80%

Width 0.62, layer 0.12, offset threshold 80%

So we don't need to adjust offset threshold when layer height is changed.

Nice! 👍

Should get the QoL label.

I thought about add absolute offset in addition to percent and reverse logic - i.e. use "overlap" instead of offset, though 15%/0.1mm means like this:

Probably it's more intuitive than setting 0.5mm/85%.
Any thoughts?

That's absolutely correct! 😃

Offset replaced with overlap (line width - offset).
