Hello!
I am using a Constrained_Delaunay_triangulation_2 in combination with a
Delaunay_mesher_2 to mesh a polygon area. 
I noticed that I can use the number_of_faces() method to get the number of
resulting faces of my mesh. However, some faces are outside of the polygon.
When I iterate over the faces with a Finite_faces_iterator, I can use the
is_in_domain() function to determine whether the face lies within the
polygon or not.
I was wondering if there is a function similar to number_of_faces(), that
returns only those faces that are within the polygon. Of course I can
iterate over the result and count all the faces where is_in_domain() returns
true, but that doesn't seem very efficient to me.
Thanks!
