MacOS X Quartz device

Description:

     'quartz' starts a graphics device driver for the MacOS X System.
     This can only be done on machines that run MacOS X.

Usage:

     quartz(display = "", width = 5, height = 5, pointsize = 12,
            family = "Helvetica", antialias = TRUE, autorefresh = TRUE)

Arguments:

 display: the display on which the graphics window will appear. The
          default is to use the value in the user's environment
          variable 'DISPLAY'.

   width: the width of the plotting window in inches.

  height: the height of the plotting window in inches.

pointsize: the default pointsize to be used.

  family: this is the family name of the Postscript font that will be
          used by the device.

antialias: whether to use antialiasing. It is never the case to set it
          'FALSE'

autorefresh: logical specifying if realtime refreshing should be done. 
          If 'FALSE', the system is charged to refresh the context of
          the device window.

Details:

     Quartz is the graphic engine based on the PDF format.  It is used
     by the graphic interface of MacOS X to render high quality
     graphics. As PDF it is device independent and can be rescaled
     without loss of definition.

     If a device-independent R graphics font family is specified (e.g.,
     via 'par(family=)' in the graphics package), the Quartz device
     makes use of the Quartz font database (see 'quartzFonts') to
     convert the R graphics font family to a Quartz-specific font
     family description.  

     Calling 'quartz()' sets '.Device' to '"quartz"'.

     Line widths as controlled by 'par(lwd=)' are in multiples of the
     1/72 inch, and multiples < 1 are silently converted to 1.
