Well, I don't actually have SVG working in FOP 0.2.5rc.
Did they adopt a new image library that isn't included?

My experience with FOP is that it doesn't support
content-width, but instead uses the 'width' attribute
as content-width.  Try setting width instead, to
a linear value with units (not %).  That's the
only scaling I've been able to achieve with FOP.
