/*!\overload
  Draws the formatted text with \a p, at position (\a x, \a y), clipped
  to \a clipRegion.  Colors from the \a cg are used as
  needed, and if not 0, *\a paper is used as the background brush.

  Note that the display code is highly optimized to reduce flicker, so
  passing a brush for \a paper is preferable to simply clearing the area
  to be painted and then calling this without a brush.

  This is a convenience function if there's no palette but just a
  color group available. If you have a palette, pass this instead of \a cg.
