pub fn screen_area_and_classic_ordering_depth3_scheduled(
vertices: [(i16, i16); 3],
depths: [u16; 3],
) -> (i32, u16)Expand description
Run hardware-safe NCLIP and compute the classic 0x155-scaled OTZ from
three cached depths without disturbing the GTE depth FIFO.
ZSF3 = 0x155 is the historical 2,048-slot ordering-table scale used by
the classic affine path. The CPU shift-add sequence is placed entirely in
NCLIP’s required MAC0 result gap, so it replaces the later AVSZ3 command
without extending the hazard schedule.
