shader_definitions.h: struct shader_base holds a radiosity block (flags,
detail level, power, emitted and tint colors) and a physics block (flags,
material type) at unchanged offsets. January's assert literals spell
shader_transparent_generic->shader.radiosity.flags and the chicago twin.
shaders.c follows the rename at its two lit-flag tests.
_rasterizer_transparent_geometry_group_draw (15,120 B) is strict exact:
widget groups via the NULL-shader render_proc union, stage-lerp component
loops, the chicago extra-layer loop kept as January's never-advancing
loop under a BUG comment, match_vassert defaults. Owner flag: two colour
component loops (debug rescale, external colour) are code-neutral where
they sit and were chosen to match the glass texscale operand order;
component loops are proven elsewhere in the same function.
Board-wide: full ninja + stable diff, +1 function, 0 regressions. The one
drift is the fuzzy park __rasterizer_model_transparent_geometry_submit
(non-exact before and after, objdiff 89.129 -> 89.008), re-measured.
