Ben, can you take a look? 

Fontconfig appears to be adding a way to distinguish a fallback /alias vs a
'real match'. Hopefully, we'll get rid of this soon.

What I had in mind is this bug (we wanted this for a long time as commented in
the file this CL is touching) :

lgtm. Note that the 'real' FontConfig back-end in Skia goes through some work to
try to implement something like this, see
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/skia/s...
for onMatchFamilyStyle and remove_weak there. It would be great to have the
matching strength exposed in FontConfig. Looking at the thread you link to, I
see that there is actually yet another class of matches which wasn't mentioned
in that thread which is 'preferred', which is when you request a font by name
but another comes back, not because it's fallback, but because the user prefers
it.
