double - sets the display mode to double buffer mode

As shipped in IRIX 6.5.7. Unchanged since IRIX 6.5.

NAME
     double - sets the display mode to double buffer mode

FORTRAN 77 SPECIFICATION
     subroutine double

PARAMETERS
     none

DESCRIPTION
     double sets the display mode to double buffer mode.  It does not take
     effect until gconfi is called.  In double buffer mode, the bitplanes are
     partitioned into two groups, the front bitplanes and the back bitplanes.
     Double buffer mode displays only the front bitplanes.  Drawing routines
     normally update only the back bitplanes; frontb and backbu can override
     the default.

     In double buffer mode, gconfi calls frontb(.FALSE.) and backbu(.TRUE.).

NOTE
     This routine is available only in immediate mode.
