Not that I'm aware of, no.  They are licensed under the GPL compatible
Apache License Version 2.0.

See these files on the branch for more:
    etc/images/material/README
    etc/images/material/LICENSE

There should be some kind of fallback for when SVG is not available,
yes.  I'm not yet sure exactly what that will look like.  The problem
with generating PBM versions AFAIK is that they don't scale, so maybe
we'd want to prefer Unicode symbols in those cases (or even emojis,
though I'm not exactly a huge fan).

We don't need to have any different variants: the svg icons will use
whatever foreground/background the current face has.

Thanks for your feedback.
