As some of you may know I'm now a huge fan of the user_defined camera in version
3.8.

A question, how does one deal with positions that are undefined for the
particular camera. For example, for a fisheye the points outside the circle are
usually deemed to be undefined and shaded as per the background.

How does one do this with the user_defined camera? That is, specify that some
positions should be assigned the background colour.
