Excellent, thanks.

I've pushed a branch scratch/svg-colors with the various fixes. Can
you please check it's working as you'd expect?

Can someone using librsvg < 1.48 please try it too? I'm including a
small script that should insert an SVG with two boxes, one follows the
theme colours the other stays with black and white.

If this all works then I suppose the documentation needs updated...
