It is meant to be that way.  It was filed as a bug report in (IIRC) the 3.1
beta timeframe, and whoever was responsible for the code at the time felt
that it should work that way.

factor should scale with the container have a difficult question to answer:
how should it scale when the container is scaled nonuniformly?
