HM_ExtAPI::GenerateMesh()– The HM_GM_OPTS_IGNORE_ERR option has been
modified. For the case of mapping errors, an attempt is made to identify HM surfaces
corresponding to mesh areas that failed to be constructed without errors. If all of
the input mesh areas except the degenerate (zero area) areas are identified, then only
HM surfaces corresponding to the mesh areas are meshed. If some of the other
non-degenerate mesh areas still can not be identified, then the entire model is
meshed.
