Un-ignored: the dev drive is the ground truth the restoration and emulator work constantly reference (DPL3/LIBDPL + VRENDER i860 renderer source, BT/RP live+dev game trees, VGL_LABS pod boot, scene/audio content). Kept in-repo for the pod-owner community. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

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.
