# GKI_WRITE -- Write a GKI metacode instruction to a graphics kernel.  If the
# kernel is inline the kernel is directly called to execute the instruction,
# otherwise the instruction is written into the graphics stream for the
# kernel.  This procedure is functionally equivalent to GKI_EXECUTE, but works
# for both inline and external kernels.
