That would depend on the style you change, if you made foo:two invisible,
you would need to regenerate the entire graphic,
if you only increased the line width, you might be able to only
regenerate foo:two and all graphical elements that
follow foo:two in sequential order of the cgm file. It would make no
difference if you defined foo:one or foo:three as first
child you would still need to process the graphic elements in the order
they are presented in the CGM.
