Moves stairs, grid, disc, tube, capsule, arch, pyramid, fence,
and tree into the existing cli_gen_mesh.cpp module. Together
with the 12 composite props extracted in 00754941 and the
anvil added in cd4bdfec, the module now contains 22 of the
28 procedural mesh primitives.
Remaining mesh handlers in main.cpp: --gen-mesh dispatcher
(cube/plane/sphere/cylinder/torus/cone/ramp), --gen-mesh-from-
heightmap, --gen-mesh-textured. Those have specialized I/O or
embedded sub-dispatch and will move in a follow-up batch.
main.cpp drops 22,681 → 21,526 lines (-1,155). Behavior
verified by re-running stairs/disc/fence/tree.
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.
