line-smooth and polygon-smooth don't match

[Peakhunter]

If I use this on forest:
polygon-smooth:0.5; line-smooth:0.5;
I get non-congruent outlines.
The polygon-smooth seems to be the problem.

This is a complex problem dealing with line simplification algorithms, basically if you have different starting points then it is very likely that the results may end up different.

Closing this for now because I do not know any computational way to match this regularly - if someone has a compelling way to do it feel free to open it back up 👍

@flippmoke - I don't think this is a simplification issue unless there's some clipping happening as well. It's not clear from the description. I'd expect stroke and fill on the same geometries to match exactly (provided smooth parameters are equal).
@Peakhunter - could you verify and/or provide more info ^

Discussion gone quite, so closing. Feel free to re-open with more details if this is still an issue.
