[vtkusers] Line on a surface

[Dženan Zukić]

You probably need to determine a plane which passes through your 2 points,
which you will then use to cut your surface and thus get a "straight" line.
However plane is not defined by 2 points but rather 3, so you either pick a
3rd point at random or minimize length of this intersection with your
surface.
