Improve docs for vtkPointSet::GetPoint(id)
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
double *vtkPointSet::GetPoint(vtkIdType id) does {return this->Points->GetPoint(ptId);};
The docs for vtkPoints::GetPoint(id) include a nice warning about not depending on the returned pointer across calls. However, the docs for double *vtkPointSet::GetPoint(vtkIdType id) show no such warning and I assumed (my bad) that the call simply returned a pointer inside the points array. So I ended up wasting almost a day trying to understand why some surfacing code I was refactoring (which included adding extra calls to GetPoint) did not work anymore :-/
