Indeed. It's as if it was yesterday that I was sitting next to you in
Vilanova i la Geltrú, making, humm, the 1.2 release in 2006?

The color-in-user-fonts are hitting some bad bugs in cairo, I need some
help from Adrian fixing those before we want that code in a release.
Adrian, if you grab the 'draw' branch of HarfBuzz, the command-lines to
reproduce are all in that issue. Basically, from what I've understood so
far, when a render_color_glyph callback returns NOT_IMPLEMENTED, things can
go really weird, including glyphs going missing. There's also leaks that
valgrind is showing me... I also am hitting assertion failures, etc, all
over the place :(. I'll try to debug, but it's been over ten years since I
understood the composer soup in cairo.
