Well, I might be the cause for that as I was going back and forth a bit
as I was experimenting.  It is useful here to know that to get the best
results there is no substitution for editing the actual files.  So I'll
continue experimenting in that direction for now.

But is there anything lacking in Emacs' SVG and/or image support?  For
example, it would be very nice to be able to just do something similar
to what you would do with CSS in a browser: give `:height "1em" and have
it work automatically.  Is it worth filing a feature request about this,
or are we happy with the state of things?

Yup.  Thanks a lot for your help!
