Composite anvil silhouette: 4-step pedestal (wide base → narrow
waist → wide cap → flat work face), each step a single addBox
call, plus a 4-vertex tapered prism for the horn extending in
+X past the face. The prism's 4 side triangles converge to a
single tip vertex (the horn point), with a sealed base square
behind it.
Defaults: length=1.0, width=0.4, hornLen=0.5, bodyH=0.5. Useful
for blacksmith shops, dwarven forges, weapon-crafting set
dressing. Brings the procedural mesh primitive set to 28.
Added directly to cli_gen_mesh.cpp — proves the modular file
accepts new primitives the same way as extracted ones.
Moves the recently-added composite-prop mesh handlers (rock,
pillar, bridge, tower, house, fountain, statue, altar, portal,
archway, barrel, chest) into their own translation unit. These
12 handlers were the most contiguous block of similar-shaped
mesh code in main.cpp.
Other mesh handlers (--gen-mesh dispatcher, fence, tree, grid,
stairs, disc, tube, capsule, arch, pyramid, from-heightmap,
textured) still live in main.cpp and may be migrated in
subsequent batches.
main.cpp drops 24,270 → 22,681 lines (-1,589). Behavior
verified by re-running rock/chest/archway/fountain.
