Class MeshTrimLoop

Delete triangles inside on/near-surface trimming curve, and then adapt the new boundary loop to conform to the loop.

[DANGER] To use this class, we require a spatial data structure we can project onto. Currently we assume that this is a DMesh3AABBTree because if you don't provide a seed triangle, we use FindNearestTriangle() to find this index on the input mesh. So, it must be a tree for the exact same mesh (!). However we then delete a bunch of triangles and use this spatial DS only for reprojection. Possibly these should be two separate things? Or force caller to provide seed triangle for trim loop, instead of solving this problem for them? (But basically there is no way around having a full mesh copy...)

TODO:

  • output boundary EdgeLoop that has been aligned w/ trim curve
  • handle cases where input mesh has open borders
