Every figure is now its current 2D frame on one flat quad, the shader's
alpha discard cutting the silhouette. It still faces south and leans by
the camera's pitch, so it reads face-on at every tilt as before.
Removes the contoured slab and the carved visual-hull models --
lib/VoxelModels.lua, tools/build_voxels.py and ~70 generated files under
assets/voxels/ (2 MB). A sprite is a drawing, not an object seen from one
side: Gen 1's overworld figures are 16x16 icons with a fixed front-on
reading, and solidifying one invents a body the artist never drew. Those
files were also the one place this mod carried a description of the ROM
art, since a carve records a sprite's silhouette pixel for pixel.
The card needs no pixel access, and the solid draw, the sun pass and the
player's occlusion silhouette now share one mesh -- which the inverted
depth test the silhouette uses requires, since self-overlap would repaint
the figure on open ground. overrides/voxels/<name>.lua still wins where a
mod ships one.
