I finally tracked this down to stuff leaked (more or less deliberately)
by Fontconfig.  Calling FcFini will clean it up; but FcFini cannot be
called safely from library code (since it cannot be called redundantly).
So I've modified sdl_viewer.cpp to call FcFini on shutdown, since that's
what I normally use to check for leaks in the library code.
