A xetex run should trigger fc-cache when needed. The original
problems of Phil Taylor were caused by misconfiguration.

This works right only if the user has write access to the cache
directory.

Later today I'll install a new font in windows and try to use it
with xetex and see whether it really works as advertised.

Of course, a button in the GUI would be easier to find. It would be
even better if xetex or fc-cache could complain and give the user a
hint if fc-cache needs to run but the cache directory is not
writable. But that is not a job for us.
