Since import_from_triangulation_3 returns Dart_handle to the /infinite
vertex/, I tried using it to separate out infinite vertex from other
vertices. But in this code
<https://gist.github.com/pranavkantgaur/9e928dc3fd5816cb891a#file-lccimport-cpp>

I find that the coordinates of infinite vertex in Linear cell complex are
different from those in Delaunay triangulation. Is it really a bug or I am
understanding it incorrectly?
