I am using CGAL 4.13 to do some 2D triangulation of an outline (I am also a
total CGAL beginner). In my case some random data originally read from
GeoJSON:

<http://cgal-discuss.949826.n4.nabble.com/file/t376086/hfx5w.png>

The triangulation is done exactly like mentioned in the CGAL user manual:
https://doc.cgal.org/latest/Mesh_2/index.html#title14

But when I fetch the triangles out of the *Mesher* (via
*mesher.triangulation()*), is do not only get the inner triangles but also
some "outer" triangles:

<http://cgal-discuss.949826.n4.nabble.com/file/t376086/FJqnh.png>

Is there a way to get only the triangles matching to the original outlines?
Like this:

Could you please guide me to some functionality in order to drop these
non-required triangles? Or am I using the completely wrong technique?

Thank you in advance.

Thomas
