DONT USE C-comments - this is included by assembly code!
hence the horrible if 0s

pixel map allocation for pazpl5
#endif

#if 0

The pixel map has 2 distinct regions, scan-conversion variables and
shading variables. The scan-conversion variables are written during
polygon processing. At end-of-frame time some computation is performed,
and what data is left is shifted into the shading variables.
