[vtkusers] vtkCubeAxesActor2D: updating with visibility changes?

[David Marshburn]

hi,

so, i have an instance of vtkCubeAxesActor2D in an application, and i want 
to turn its visibility off at times.  when i do this, the pipeline doesn't 
seem to be updated/a redraw doesn't seem to be forced.  i've tried calling 
Modified on the axes actor, too, but even that doesn't seem to work.  if i 
do anything else to the scene (change the view or change some other actor, 
for instance), the axes' visibility visually updates correctly.  is 
vtkCubeAxesActor2D a second-class citizen for modified times and 
propogated updates?  what am i missing, please?

this is with vtk 4.4 in java.

thanks!
