I think so too, and we can just set them equal to the wxXXXX variants
as well, to maintain backwards compatibility.

SVG actually doesn't allow multi-line text except with explicit
additional lines (i.e. no word wrap), so each could actually be a
separate text entity, positioned separately. Writing out the SVG will
be a lot easier than reading it in.
I've made some major modifications to the SVG rendering for both the
text and the splines. They both now replicate exactly the output of
wxArt2D. In the case of the splines, it uses vector splines instead of
polylines, which looks quite good. I've also made it so the font
family, style, alignment, etc. are correctly outputted to the SVG.
Here are some screenshot comparisons:

I'll add them once I get CVS access.
