According to MSDN, the "pending" error is to give the calling app a
chance to select the matching font back into the DC if the information
wasn't cached.  I think that the get_script_cache function is broken,
in that it should return the pending error if the HDC isn't provided,
since the HDC in the cache might no longer have the same font
selected.  However maybe some applications don't deal with the pending
case properly.
