0027991: Modeling Algorithms - BRepGProp_Face crashes on face without geometric surface

Browse Source 
BRepGProps now ignores faces without geometric surface to avoid access violation.
BRepExtrema_DistShapeShape::DistanceMapMap() now skips comparison between void bounding boxes.
BRepBndLib::Add() now ignores useTriangulation flag for faces without geometric surfaces, and uses triangulation if any for updating of the box.
