I think legacy should win here. This is CGM:1999 territory... I see
more harm than good from such a change (if doable).

After thinking about it some more, I expect the long time CGM users
(Dave, Lofton, Dieter, Don etc...) to say "don't change the default".

Right, I think Lofton has some ideas about this. Note that we can
change the WebCGM 2.0 wording, but not the PPF.
