vtk 3.1: vtkInteractorStyleUser callbacks

[John Biddiscombe]

> (Btw, what is vtkTypeMacro and why whould/should I want to use it?)

If you get a pointer and you're not sure if its polydata, structuredpoints
or whatever, you can

if (object->IsA(vtkPolyData.....) look in vtkset.get.h for defs (right at
the end). And the vtkIsTypeMacro you asked me about is just an older version
I haven't removed from my code yet
