A more general invalidate-cache-for-specified-font-face function
would be very useful. It would help with use of multiple-master-type
font technologies. I hit this situation when implementing my wrapper
for the Hershey fonts <https://github.com/ldo/hersheypy> for Cairo: to
use different line widths, I had to load multiple copies of the same
font to get around Cairo’s caching.
