- * eOrg->Onext <- OLD( eDst->Onext )
- * eDst->Onext <- OLD( eOrg->Onext )
- * where OLD(...) means the value before the meshSplice operation.
- *
- * This can have two effects on the vertex structure:
- * - if eOrg->Org != eDst->Org, the two vertices are merged together
- * - if eOrg->Org == eDst->Org, the origin is split into two vertices
- * In both cases, eDst->Org is changed and eOrg->Org is untouched.
- *
- * Similarly (and independently) for the face structure,
- * - if eOrg->Lface == eDst->Lface, one loop is split into two
- * - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one
- * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected.
- *
- * Some special cases:
- * If eDst == eOrg, the operation has no effect.
- * If eDst == eOrg->Lnext, the new face will have a single edge.
- * If eDst == eOrg->Lprev, the old face will have a single edge.
- * If eDst == eOrg->Onext, the new vertex will have a single edge.

- * - in any case, we must leave some record of vEvent in the dictionary,
