[Paraview] setting graphical window size

Ok, I accept that - it was simply the appearance that the axes 
indicators only altered in size with vertical scaling (but not with the 
horizontal scaling) that I thought might be a bug. Hadn't actually 
noticed this though until I created the examples - was not the central 
tenet of the issue I was raising

They are only that dramatic because I was creating a deliberate 
exaggerated example

This is the issue exactly "then resize the paraview windows to mimic the 
aspect ratios you are using" - How do I do that for a specified 
resolution ?
I think we have come back full circle to the issue I was raising. And 
that is how do I set the GUI/View/Image window to a specified resolution 
? At the moment the only way I can see is run a script, after altering 
the size of the window with the mouse, to see what the current size is 
and then repeating the process until the desired resolution is obtained 
- a little bit iterative and clumsy.

Clearly from your description a scene is composed of different forms of 
actors (2D & 3D) and that these behave differently when scaled in the 
"save screenshot" command. Therefore in order to achieve repeatability I 
need to be able to set my View/scene/image window to my desired size 
each time I load paraview so that I am seeing a true representation of 
what I am creating and thus avoiding any scaling at the "save 
screenshot" stage.

Ideally I'd like the ability to specify the scene/image window size 
directly or failing that to see its size in real time as I drag the 
borders with the mouse to my desired size.

Thanks
