I think we agreed that the change would negatively impact performance; I'm
surprised it is as small an effect as this though; I consider this an
acceptable result pending changes to the FreeType API that would give this

Please fix the problem in the right spot and stop attempting to work around
things in the X interface. I'll be happy to let you stick any patches you
like into the X code as long as they use published FreeType interfaces.
Anyway, Mozilla already has an good solution for font performance issues
when running against this X server.

As I said, until we get the fix pushed back upstream, we will have ongoing
issues with kludging around things. Keeping a private version of FreeType
is not an acceptable answer to this minor performance problem.
