[vtk-developers] 2D vs 3D rubber band interactor style

[David E DeMarle]

The rubber band interactor styles should definately be unified. I stole from
rubberbandzoom to make rubberbandpick and later the other two were stolen
from one of those.

They should all have a common helper class which does the xor rendering of
the rubber band (and whatever else is common) and leaves the functionality
differences to the existing classes.
