**usage: r_font   opflg eflag ltime    TextSize TextFace TextMode**

R_FONT is a REALTIME operator. It specifies the size (TEXTSIZE), style
(TEXTFACE), and transfer mode (TEXTMODE) for the active display font.
TEXTSIZE is specified in pixel units.  TEXTFACE is a font code, which is
dependent on the screen hardware available; the following values will
generally be recognized:
          0 - system font
          1 - ??
   TEXTMODE is a flag with the following meaning:
          0 - replace screen pixels with font pixels
          ? - AND screen pixels with font pixels
          ? - OR screen pixels with font pixels
          ? - XOR screen pixels with font pixels
