The heart of Tiled support: load a map and draw it.
- rt_tmap model (Tmap/TmLayer/TmTileset in tiled.ludic): map header + ordered
layers (dense int32 GID arrays, heap-allocated to w*h, lifting the 96x64 cap)
+ tilesets. Built from the intermediate Value tree, so the TMX and TMJ paths
both feed it.
- GID resolver (Tiled.resolve): gid -> (tileset, localId, flipH/V/D); the three
flip flags masked off before the local-id lookup, returned alongside. gid==0
is empty.
- Image-backed render (Tiled.draw): every visible tile layer in file order,
blitting each tile from its tileset image with flips applied at draw.
- Compatibility projection (Tiled.project / auto on load): a designated
collision layer projects to the legacy byte tilemap ('#' solid, '=' one-way
via the oneway property, ' ' empty) so Grid.*/Path.*/esys_move are unchanged.
- Tiled.load resolves external tilesets + images relative to the map file and
auto-projects a collision/solids/walls layer.
- The grid and physics_tiles demos now run off a loaded map (grid_maze.tmx /
physics_map.tmx) instead of hand-authored Map.row strings, byte-identically.
Two compiler fixes fell out of this (see the changeset):
- emit_index_addr set g_addr_ty before evaluating the index, so slice[obj.field]
came back mis-typed; set it last, like the raw-pointer branches.
- @strcmp was declared by both the world table and the fs prelude; centralise
it in the head prelude so a game that uses Fs/Path links.
Proven by library/tiled_p1.ludic (14 assertions: loads+renders Kenney map
identically from .tmx and .tmj, flip mirroring) + the converted grid/
physics_tiles demos. x test: 92 passed; self-host bootstrap fixpoint intact.

Draws every visible tile layer in file order to the framebuffer, offset by the camera (camx, camy), blitting each tile from its tileset image and applying the GID's flip flags at draw time.
