There is a cairo snippet that loads a static SVG file, but I was
thinking... the red ship and the blue ship are pretty much identical,
but for different colors.  Do you know if the SVG spec (or something
else?) allows for "parameterized" SVG, so that I can say something like
"load the ship.svg file with parameters (primary_color = #FF66CC,
active_layers = [ship, shields, exhaust], frame = 2)"?

I suppose that one possibility is to have a "master template" .svg file
and then use something like m4 or python to generate instances
(also .svg files) of the template.  But that doesn't seem to allow
"dynamic" instantiation, say if I wanted to "skin" my ship through the
game UI, not through running a python script.

Thoughts, anyone?

[smacks forehead] Of course, RTFM!  :)
