[Per Zetterlund <>]

Maybe I'm doing something wrong,
but I get:

error: no match for ‘operator+=’ (operand types are
‘CGAL::Point_3<CGAL::Epick>’ and
‘__gnu_cxx::__alloc_traits<std::allocator<CGAL::Vector_3<CGAL::Epick>
> >::value_type {aka CGAL::Vector_3<CGAL::Epick>}’)

So I have to do

Point& p = vertex.point();
p = (p + Vector(deltaX, deltaY, 0));
