Hello darkness my old friend ...
Diving into exact triangle intersection code, that is exactly bugged !
Revisiting the whole approach, hopefully much much simpler in the end

You may think that once you have exact predicates it is piece of cake, but there is a surprisingly long list of particular cases: trlgs can be in the same plane, touch along a vrtx, an edge, isect can be a single point, a segment, a little triangle, it can even be a hexagon !
Seeing some light at the end of the tunnel... Seems that a reasonably short program can handle all the cases (but it does not fit in the margin, euuu I mean in a tweet !)

What's that ?
The raw scanner data for armadillo.
Can we reconstruct the armadillo from it ?

Step 1: Filter outliers
Step 2: smooth a bit
