This may be true and will cause the problem to manifest on most
websites rather than just on ones that ask for `Times' or `Helvetica'
explicity. However, even if we fix Mozilla then we'll still have
problems with those latter sites.

This is not a hack, and I resent you describing it that way.
It's the correct solution; we add the missing piece of information to
the interface. Or do you disagree with some part of my rationale ?
If so, please come out and explain !
But yes, if you don't use pango for everything then you have to find
the places in Mozilla where it uses fontconfig and change those too,
to pass the new flag. I haven't done that at this stage because it
wasn't relevant to the configuration in Ubuntu.
Alternatively you might say that the default is wrong, and that
instead we should edit the programs that have (or whose documents
have) a specific idea of what the metrics are going to be.
Thanks,
Ian.
