  11.      These routines give the user a method of updating screens with reasonable
  12.      optimization.  They keep an image of the current screen, and the user
  13.      sets up an image of a new one.  Then the rreeffrreesshh() tells the routines to
  14.      make the current screen look like the new one.  In order to initialize
  15.      the routines, the routine iinniittssccrr() must be called before any of the oth­
  16.      er routines that deal with windows and screens are used.  The routine
  17.      eennddwwiinn() should be called before exiting.
