      Sets the page configuration (optional).  If an individual parameter
      is zero then that parameter value is not updated.  Not all parameters are
      recognized by all drivers and the interpretation is device-dependent.
      The X-window driver uses the length and offset parameters to determine
      the window size and location.  The length and offset values are expressed
      in units that are specific to the current driver. For instance:
      screen drivers will usually interpret them as number of pixels,
      whereas printer drivers will usually use mm.
      This routine, if used, must be called
      before initializing PLplot.
