- Image layers: <imagelayer> renders with parallax + optional repeatx/repeaty
tiling across the view; the image loads relative to the map file. Group layers
flatten at build (children render in file order); layer offset/opacity/tint are
queryable (Tiled.layer_kind / layer_offsetx / layer_offsety / layer_opacity /
layer_tint), a group's tint applying recursively.
- Orientation transforms: Tiled.cell_x / Tiled.cell_y compute a tile cell's
screen position for orthogonal, isometric ((x-y)*tw/2, (x+y)*th/2), staggered,
and hexagonal (rows step by (tileh+hexsidelength)/2, alternate rows shoved per
staggerindex) — the tile draw now places cells through them.
- Wang: exported Wang-set GIDs are ordinary GIDs and resolve through the standard
GID resolver; the terrain-corner authoring concept is editor-side (design cut).
Proven by library/tiled_p5.ludic (14 assertions) over the real
isometric_grass_and_water.tmx (iso + Wang) and hexagonal-mini.tmx, plus a
hand-authored image+group fixture. x test: 96 passed.
