[vtkusers] Can a vtkActor be added to more than one renderer

[Kall, Bruce A.]

I seem to be able to add some type of actors to multiple renderers 
(lines, image
volumes etc), but not all.

In particular, if I create axial, sagittal and coronal actors like in 
Medical3.cxx and
add them all to the same rendered they work fine.  If I add each one to 
a different
renderer, they all work fine.  But if I attach any one of them more than 
once,
the displayed 'plane' shows up as all white on any renderers after the first
one using it is rendered (e.g, if I attach the three image actors in 2 
or more renderers,
they all display fine on the first renderer, but show up as an all-white 
plane on
any other renderers).  Is there a way to use an image-type actor like 
these on more
than one renderer at a time?

Any suggestions?

Thanks,
Bruce
