When running the example parameter file for simulating the BBH merger GW150914 (with modifying the .rpar file to have a non-zero out3d_every variable), the surface .vtk files from the QuasiLocalMeasures thorn are not spheres as expected, but some odd shape.

Roland has reproduced this bug, and suggested commit 56a98ded "QuasiLocalModes: Simplify VTK output routine to speed up build times" may be at fault.
