OCC provides that information through brepgprop_VolumeProperties,
brepgprop_SurfaceProperties and brepgprop_LinearProperties.
There is a CentreOfMass() method that returns a vector. There also exists a
Mass() method that gives either the volume, surface or length of the entity.
I call them through PythonOCC, but if that interface was provided by Gmsh API
then I would not need to read the same BREP file both with PythonOCC and Gmsh.
BTW, I love the new Gmsh API :-)
