Epsilon in PointwiseMapper
On numerous occasions now we have run into the issue of importing a double TetrahedralMesh and float SurfaceMesh. Usually the original data was in double, the .msh file format supports double. .vtk supports double. But SurfaceMesh's often seem to be read in as 32 bit floats.
Then the PointwiseMap is used resulting in a static/unmapped SurfaceMesh. None of the points were found to be on the TetrahedralMesh because of its epsilon.
