The patch needs to be against head. There is limited RTL support for
OSD text in head, it should be used when the fribidi2 library isn't
available, and disabled when it is (see ConvertFromRtoL in OSDTypeText).
Also, is DrawString the best place for this? I think it would make
sense to do the conversion earlier when the text is set, DrawText()
itself should run as quickly as possible.
