#include <tos.h>

int Blitmode( int mode );

  <mode> is the new blitter mode, or -1 to keep old value.
         0 = use software.
         1 = use blitter chip.


Function gets or sets the blitter mode.  It returns the old value:
  Bit 0  Use blitter chip (1) or software (0).
  Bit 1  Blitter chip installed (1).

Note: The BLITTER chip is used to perform bit-block transfers, which
      are used primarily for screen image manipulation.
      Blitmode() is defined even on Ataris which lack a BLITTER chip.
