doublebuffer - sets the display mode to double buffer mode

As shipped in IRIX 6.5. First release of IRIX 6.5.

NAME
     doublebuffer - sets the display mode to double buffer mode

C SPECIFICATION
     void doublebuffer()

PARAMETERS
     none

DESCRIPTION
     doublebuffer sets the display mode to double buffer mode.  It does not
     take effect until gconfig 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; frontbuffer and
     backbuffer can override the default.

     In double buffer mode, gconfig calls frontbuffer(OFF) and backbuffer(ON).

NOTE
     This routine is available only in immediate mode.
