Looks good, thanks.  What's still missing is my suggested fourth mode
(not present in the support for other libraries needed by FreeType),
namely the `no-default' option to have compiled-in SVG code without
providing a default library.

I think we shouldn't do this; it's getting too complicated.  I believe
that my suggested `no-default' mode is a simpler solution; the user
registers the library hooks at run-time, and that's it.  Everything
else has to be done on the user side (this is, providing any necessary
wrapper and/or port files and setting up correct linking).

If we are following my route, all of your suggestions are not
necessary, I think.
