title: POV-Ray: Setting output resolution or width/heigh ratio within the script
body: <p>I have a code that generates a bunch of <code>*.pov</code> files for visualization using POV-Ray. Unfortunately, they are of different aspect ratios (width/height). That information is in the script in the form of the up/right vectors. However, when I render a script without any extra parameters, i.e. through <code>povray test.pov</code>, POV-Ray forces the standard 4/3 aspect ratio. Therefore, images are distorted. </p>
  
  <p><strong>Question:</strong> Is there any way that the script may request a certain aspect ratio or resolution? </p>
