render_textured.py samples the game textures with the quads' texu/texv/texz
planes, z-buffered. Empirical finding: the planes are texscale-encoded
(2^16) homogeneous coords needing the exact perspective_divides mapping
(texu/texz * .Cturn_z_to_tex from FOOTER.SS) -- measured texu/texz ~0.12 on
the ground quad. That final texel-coordinate calibration is a precise
reverse-engineering step against EOF.C, not a guess; left as the last mile.
The verified M3 result is the texture DECODE: the netdeath textures are real
game art (texstore.py). Geometry + texel format are both solved from the
live wire.
