[Paraview] vtk renderer

[Sgouros, Thomas]

Hi Sebastien:

I'm afraid I don't understand what you're saying here. Why would the
container grow due to the setup of my css? I thought the way it works is
that I resize the window, and SIzeHelper.onSizeChange() gets called. I use
that function to call .resize() on the renderers and the vertical works
perfectly, but the horizontal only goes one direction.

Here's the entire hierarchy. There is no external CSS, so this is
everything. I went back and tried to make the height and width parallel,
set the same way. What I observe is that as I change the window size, the
height (the number '686' in the image) changes when I make the window
smaller or larger, but the width (the number '565') only changes when I
make the window wider. When I make the window narrower I have to refresh
the page to get the new width and then it looks right. Can you identify
what isn't the same between width and height in my hierarchy?

Thanks,

 -Tom
