[vtkusers] Interaction through python and vtkInteractorStyleUser

[David Gobbi]

Hi All,

I finally have vtkInteractorStyleUser at a point where I'm more or
less happy with it.  It allows you to hook into pretty much all of
the interaction events from Tcl, Python, or C++ without having to
write a subclass of vtkInteractorStyle.  It has evolved significantly
over the last few months.

An example of how to use it through python is provided in 
vtk/contrib/examplesPython/SliceViewer.py.  Currently there is
no tcl example (through tcl you would usually use the
vtkTkRenderWidget instead).  

This example also demonstrates how to do interaction with 
a vtkImageWindow (well, not quite... it draws the images in
a RenderWindow instead).

 - David
