Hi Jason,

I'm sorry I haven't responded to this before now.

Those all look really great to me.

Why don't we just set you up with commit access and then you can own
the command-line interface for this program. You seems to have done a
better job of interface design than I have.

And then you could also go commit your DPI fixes for libsvg-cairo and
add the missing --dpi option.

That also sounds good.


PS. In the last couple of days I committed some code to librsvg which
improves its new support for rendering with cairo and adds an
rsvg-cairo program which is quite similar to svg2png. That work may
end up obviating libsvg-cairo, but it's not quite ready to do that
