Gets overall metric information for a font. Since the metrics may be
substantially different for different scripts, a language tag can
be provided to indicate that the metrics should be retrieved that
correspond to the script(s) used by that language.
If font is NULL, this function gracefully sets some sane values in the
output variables and returns.
