[vtkusers] rendering transparency problems

Hi All,

I am have a multi-layered render window and I am having problems with
the top renderer not rendering the actor clearly-it shows up speckled,
as if the actor behind it is showing through.   The topology is not
coincident, so I am not sure where the problem is.


If I set the renderer of the front layer to erase using
myFrontRenderer.EraseOn(), then it all renders cleanly, but it also
makes any part of that layer that should be logically behind the back
layer visible.


I also put the actors all into the same renderer and it still looked


Any suggestions on how I can achieve a cleanly rendered view?   I've
attached two images that illustrate the problem.
