getClosestFacetAtCoordinates returning null most of the time

I think it is working as expected (albeit not how you would like it to work): When using facets, the mesh bounding volume is subdivided into tiny cubes, depending on a number of parameters (partitioningBBoxRatio, partitioningSubdivisions, …). When checking a point P for a closest facet, the function looks for the cube containing P and compute the distances between P and each facet of this cube and returns back the facet with the minimum distance to P. So, there are two important things to not…
