[vtkusers] How to make a image slice renderer full fill in a renderWindow?

[Shawn Waldon]

Hi Yihui,

I don't know if there is a built-in easy way to do this.  In the tomviz
project we set the camera to orthographic projection and then set its view
bounds so that the image fills the whole area (or as close as possible if
the aspect ratios are different).  If someone knows a better way to do
this, I would like to learn about it too.

HTH,
Shawn
