[vtkusers] Something Fishy About vtkSelectVisiblePoints

[Erik Sobel]

I am running vtkSelectVisiblePoints on a simple cube.  Sometimes it does 
not correctly return all the visible points unless I run it first with the 
actor's representation set to "points" and then run it again with the 
representation set to "surface".  I've tried to get the same effect by 
setting the "Modified" flag on the render window, renderer, actor, 
properties, etc nothing else seems to have the same effect of "resetting" 
the vtkSelectVisiblePoints.

The problem is most noticeable when you slide part of the points off the 
render window and then back on again.

Anyone ever see this before?
