[vtkusers] need speed using ImageData & ImageActor

[Howard Katz]

Hello experts,

I have used LODActor and Iren->SetDesiredUpdateRate in the past to speed up 
rendering times for things like meshes etc. and this has helped quite a bit

However I now have three 2D vtkImageData of size 300 by 100 one on top of 
the other and they are taking way too long to render
I need to use ImageActor and not ImageViewer (because I have three imagedata 
actors not just one)
So how can I speed thigns up?
I tried clipping it down using SetDisplayExtent, but its still way too 
slow...
=(

any ideas?? Thank you!
