[vtkusers] Draw an object using millimeter as unit

[Cory Quammen]

Specifying the height of the cone as 10 does not mean that it is 10
pixels high, for example, or 10 of any other screen unit. Units in VTK
mean whatever you want them to mean. Millimeters, meters, feet,
cubits, anything. The only thing you need to do is be consistent in
how you interpret sizes in VTK.

Best,
Cory
