You probably do -- we actually have very little interest in Cairo as a
SVG backend; instead, we are using Cairo as the general rendering
engine for our entire browser.  The above changes and additions were
not motivated by SVG at all; instead, they were based on things that
we needed (or thought we needed) to solve some other problems.  So
waiting for us to "finish SVG" to give feedback for cairo is probably
not useful, as that is not our goal.

No, you can't.  If you do a simple ucs2 -> glyph mapping, you are
trading one toy font api for another toy font api.  Someone will run
into the same brick wall and have the same "dead code" problem that
you ran into, not to mention adding a -ton- of code to cairo that
someone has to maintain that once again doesn't actually solve the
whole problem!
