Yes, there is a way to prohibit new points on the boundary, and that's
what I'd recommend doing:
http://documen.tician.de/meshpy/reference.html#meshpy.triangle.build
What you want is 'allow_boundary_steiner=False', I think. Of course then
you need to put enough points on the boundary in your initial mesh.
