Short edges

[Stem]

I just checked the code (long tracking) and it came from the fact that thin faces are discarded if Sum/Longest =< 1.001
Sum = sun of all face's edges
Longest = the most long edge in the face

From an end_user point of view, that brings in inconsistency, as different sized models will have a different limit on the smallest edge that can be added.
It looks like whatever scale I use, I am going to be hit with this issue while trying to add small detail/edges.
