Entities can now specify per-tile sprite indices via the sprite_grid
property. When set, each tile in a multi-tile entity renders its own
sprite from the texture atlas instead of the single entity sprite.
API:
entity.tile_size = (3, 2)
entity.sprite_grid = [[10, 11, 12], [20, 21, 22]]
entity.sprite_grid = None # revert to single sprite
Accepts nested lists, flat lists, or tuples. Use -1 for empty tiles.
Dimensions must match tile_width x tile_height.

Entities can now span multiple grid cells via tile_width and tile_height
properties (default 1x1). Frustum culling accounts for entity footprint,
and spatial hash queries return multi-tile entities for all covered cells.
API: entity.tile_size = (2, 2) or entity.tile_width = 2; entity.tile_height = 3

Textures can now specify display_size and display_origin to crop sprite
rendering to a sub-region within each atlas cell. This supports texture
atlases where content doesn't fill the entire cell (e.g., 16x24 sprites
centered in 32x32 cells).
API: Texture("sprites.png", 32, 32, display_size=(16, 24), display_origin=(8, 4))
Properties: display_width, display_height, display_offset_x, display_offset_y

to_bytes() returns raw uint8 cell data as Python bytes object.
from_bytes(data, size, enum=None) is a classmethod that constructs
a new DiscreteMap from serialized data with dimension validation.

UIFrame, UICaption, and UISprite now accept "pos" as an alias for "position"
in the animation property system. UICaption and UISprite gain Vector2f
setProperty/getProperty overrides enabling animate("pos", (x, y), duration).
Color compound animation (fill_color, outline_color) was already supported.

Breaking API change: removes 4 camelCase function aliases from the mcrfpy
module. The snake_case equivalents (set_scale, find_all, get_metrics,
set_dev_console) remain and are the canonical API going forward.
- Removed setScale, findAll, getMetrics, setDevConsole from mcrfpyMethods[]
- Updated game scripts to use snake_case names
- Updated test scripts to use snake_case names
- Removed camelCase entries from type stubs

Removed custom __eq__/__ne__ that allowed comparing enums to legacy string
names (e.g., Key.ESCAPE == "Escape"). Removed _legacy_names dicts and
to_legacy_string() functions. Kept from_legacy_string() in PyKey.cpp as
it's used by C++ event dispatch. Updated ~50 Python test/demo/cookbook
files to use enum members instead of string comparisons. Also updates
grid.position -> grid.pos in files that had both types of changes.

Grid.position was a redundant alias for Grid.pos. Removed get_position/
set_position functions, getsetters entry, and setProperty/getProperty/
hasProperty branches. Updated all tests to use grid.pos.

sprite_number was a legacy alias for sprite_index. All code should use
sprite_index directly. Removed from getsetters, setProperty/getProperty/
hasProperty in UISprite and UIEntity, animation property handling, and
type stubs.

Add `collide` kwarg to Grid.find_path() and Grid.get_dijkstra_map() that
treats entities bearing a given label as impassable obstacles via
mark-and-restore on the TCOD walkability map. Dijkstra cache key now
includes collide label for separate caching. Add Entity.find_path()
convenience method that delegates to the grid.

GridView is a new UIDrawable that renders a GridData object independently.
Multiple GridViews can reference the same Grid for split-screen, minimap,
or different camera/zoom perspectives on shared grid state.
- New files: UIGridView.h/cpp with full rendering pipeline (copied from
UIGrid::render, adapted to use grid_data pointer)
- Add UIGRIDVIEW to PyObjectsEnum
- Add UIGRIDVIEW cases to all switch(derived_type()) sites:
Animation.cpp, UICollection.cpp, UIDrawable.cpp, McRFPy_API.cpp,
ImGuiSceneExplorer.cpp
- Python type: mcrfpy.GridView(grid=, pos=, size=, zoom=, fill_color=)
- Properties: grid, center, zoom, fill_color, texture
- Register type with metaclass for callback support
All 258 existing tests pass. New GridView test suite added.

Game code uses standard Python file I/O to mcrfpy.save_dir with no platform
branching. On WASM, builtins.open() is monkeypatched so writes to /save/
auto-sync IDBFS on close, making persistence transparent.
API: mcrfpy.save_dir (str), mcrfpy._sync_storage() (auto-called on WASM)

- SoundBuffer.gain(factor): new DSP method for amplitude scaling before
mixing (0.5 = half volume, 2.0 = double, clamped to int16 range)
- Fix sfxr square/saw waveform artifacts: phase now wraps at period
boundary instead of growing unbounded; noise buffer refreshes per period
- Fix PySound construction from SoundBuffer on SDL2 backend: use
loadFromSamples() directly instead of copy-assign (deleted on SDL2)
- Add Image::create(w, h, pixels) overload to HeadlessTypes and
SDL2Types for pixel data initialization
- Waveform test suite (62 lines)

Extends the shade_sprite module (for merchant-shade.itch.io character
sprite sheets) with procedural faction generation and asset management:
- FactionGenerator: seed-based faction recipes with Biome, Element,
Aesthetic, and RoleType enums for thematic variety
- AssetLibrary: filesystem scanner that discovers and categorizes
layer PNGs by type (skins, clothes, hair, etc.)
- TextureCache: avoids redundant disk I/O when building many variants
- CharacterAssembler: HSL shift documentation, method improvements
- Demo expanded to 6 interactive scenes (animation viewer, HSL recolor,
character gallery, faction generator, layer compositing, equipment)
- EVALUATION.md: 7DRL readiness assessment of the full module
- 329-line faction generation test suite
Assets themselves are not included -- sprite sheets are external
dependencies, some under commercial license.

Replaced the NotImplementedError stub with a full animation
implementation. Entity3D now supports animating: x, y, z,
world_x, world_y, world_z, rotation, rot_y, scale, scale_x,
scale_y, scale_z, sprite_index, visible.
Added Entity3D as a third target type in the Animation system
(alongside UIDrawable and UIEntity), with startEntity3D(),
applyValue(Entity3D*), and proper callback support.

EntityCollection3D now has API parity with UIEntityCollection:
- pop(index=-1): Remove and return entity at index
- find(name): Search by entity name, return Entity3D or None
- extend(iterable): Append multiple Entity3D objects
Also adds `name` property to Entity3D for use with find().

screen_to_world() previously only intersected the Y=0 plane.
Now accepts an optional y_plane parameter (default 0.0) for
intersecting arbitrary horizontal planes.

The root cause was PyViewport3DType being declared `static` in
Viewport3D.h, creating per-translation-unit copies. Entity3D.cpp's
copy was never passed through PyType_Ready, causing segfaults when
tp_alloc was called.
Changed `static` to `inline` (matching PyEntity3DType and
PyModel3DType patterns), and implemented get_viewport using the
standard type->tp_alloc pattern.
