Comment (by strk):

 Another idea I'm having is to have a different signature all together. The
 thing is toTopoGeom currently does BOTH the work of TopoGeo_addWhatever
 AND something else, we could encode that "something else" into its own
 function such function could be used in by users who have trouble building
 up their own TopoElementArrays, it could return a TopoElementArray so that
 its return value can be fed to CreateTopoGeom directly.

 Evil as usual is in the details: how do you decide whether or not you
 accept the components ? Should we compute hausdorffdistance of the
 topogeometry::geometry and the input geometry to tell if the result is
 acceptable ? Possible outcomes: we pick elements which also covers space
 OUTSIDE of the input geometry; the sum of all returned elements is not
 enough to cover all the space of the input geometry.
