Using a bgm in this context does not work.

*) The bgm file is always treated as "isotropic" :

in void PostViewField::operator() (double x, double y, double z,
SMetric3 &metr, GEntity *ge=0) :
virtual bool PostViewField::isotropic () const always return true
as v is null!

*) the bgm is not taken into account. In fact it tries to 
get a metric from some """formula""" (see BGM_MeshMetric) 
just like in  http://www.geuz.org/pipermail/gmsh/2012/006970.html

It would be really great if we can use bgm metrics...
