Back face culling

In MB86R02 'Jade-D', a triangle direction can be defined and a mode in which drawing for the back

face is inhibited (back face culling) is supported. The on/off operation is controlled by the GMDR2[0]

setting. GMDR2[0] must be set to 1 only when back face carling is required. When back face culling is

not required such as in 'line,' 'point,' and 'polygon primitive,' GMDR2[0] must be set to 0.
