This isn't answering your detailed question, but an alternative (you are
maybe already aware of) is to capture the entire screen instead of a
single widget. This is done by leaving the Pixmap's widget nil (skipping
the [aPic setWidget: ] message). You move all your displays so the
entire screen looks nice, then set your simulation running and capture
the whole business.

However, in Windows there was a problem that I am not sure ever got
entirely fixed. The pixmap would not get the right part of the screen
and add a black space at the bottom. You can work around this if you're
putting the movie in PowerPoint, etc.
