[Gmsh] How to do Coherence; through the library API?

[Takuya OSHIMA]

Hi,

I am using Gmsh 2.5.0 thgough the C++ API and am not able to figure
out how to do the equivalent operation of Coherence; directive of Gmsh
scripting language. Since It seemed to me that ReplaceAllDuplicates();
(the function that seemed to do the actual job of Coherence;) did not
update the corresponding GModel, I had to destroy the GModel once and
re-import the internal structure by

  GModel *m = new GModel;
  m->addVertex(...)
  ...
  ReplaceAllDuplicates();
  m->destroy();
  m->importGEOInternals();

which is obviously not efficient and discards some internal
attributes. Besides I had to modify the Gmsh source as attached in
order to deal with embedded entities. Do I have to do this way, or am
I overlooking something?
