#3319 new enhancement

Improve TopoGeo_addPolygon step of finding polygon-covered faces

Description

In a case I'm looking at, adding 50 or so polygons spends 70% of its time finding the faces that belong to the polygon.

The code constructs polygons of each face to extract their point on surface for then checking which surface points are contained in the original polygon.

This step could be improved by improving the "point-on-face-surface" routing, which might not really need to build the whole polygon.
