#3319: Improve TopoGeo_addPolygon step of finding polygon-covered faces
-------------------------+---------------------------
 Reporter:  strk         |      Owner:  strk
     Type:  enhancement  |     Status:  new
 Priority:  medium       |  Milestone:  PostGIS 2.3.0
Component:  topology     |    Version:  trunk
 Keywords:               |
-------------------------+---------------------------
 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.
