Writes/reads to the
texture map memory is
done through fifo since
the texture map chip
might be doing something
with that memory at the
time. This sets texture
TF_FIFO_THRESH map write/read fifo

that FIFO needs to be
serviced and then may
accept more data from
either frame buffer or
CPU. Overrides default
video FIFO threshold (to
signal FIFO is almost
empty/full)
