If you don't specify the angle at all, then this is not the case. Doubling
the right vector expands the horizontal view area without changing the
vertical area.

We had a discussion about this a month or two ago, and your comment is only
true when certain other properties of the camera are specified. I believe
this includes the angle keyword (since it specifies the horizontal angle,
overriding the up/right vector lengths), and *possibly* the direction
keyword.
