-- the sensitivity type Sensitivity.
-- The array of points is the outer polygon of the geometric face.

---Purpose: Computes the depth values for all 3D points defining this face and returns
-- the minimal value among them.
-- If the "minimal depth" approach is not suitable and gives wrong detection results
-- in some particular case, a custom sensitive face class can be implemented at application level
-- that overrides default ComputeDepth() behavior.
