Here are two images showing the results of the script posted on 
povray.text.scene-files, solving this problem.

The first one shows the result, that is, a box fitted into view.
The second one illustrates the method, showing the constraints, etc... 
explained in greater detail in the script.

I'm posting this in case anyone needs it in the future...
