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

When transferring an entity to a new grid via entity.grid = new_grid,
the entity was removed from the old grid's spatial hash but never
inserted into the new one. This made it invisible to spatial queries
on the destination grid.

GridLayer, UIGridPoint, and GridChunk each stored a raw GridData* that
could dangle if the grid was destroyed while external shared_ptrs
(e.g. Python layer wrappers) still referenced child objects. The
destructor now nulls all parent_grid pointers before cleanup. All
usage sites already had null guards, so this completes the fix.
These were the last three unfixed bugs from the memory safety audit.

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

Layers with z_index <= 0 now render below entities (ground level), and
only layers with z_index > 0 render above entities. Previously z_index=0
was treated as "above entities" which was unintuitive -- entities stand
on ground level (z=0) with their feet, so z=0 layers should be beneath.
Changed in both UIGrid.cpp and UIGridView.cpp render methods:
- "z_index >= 0" to "z_index > 0" for break condition
- "z_index < 0" to "z_index <= 0" for skip condition

Fixes a systemic bug where Python tp_getset property setters bypassed the
render cache dirty flag system (#144). The animation/C++ setProperty() path
had correct dirty propagation, but direct Python property assignments
(e.g. frame.x = 50, caption.text = "Hello") did not invalidate the parent
Frame's render cache when clip_children or cache_subtree was enabled.
Changes by file:
- UIDrawable.cpp: Add markCompositeDirty() to set_float_member (x/y),
set_pos, set_grid_pos; add markDirty() for w/h resize
- UICaption.cpp: Add markDirty() to set_text, set_color_member,
set_float_member (outline/font_size); markCompositeDirty() for position
- UICollection.cpp: Add markContentDirty() on owner in append, remove,
pop, insert, extend, setitem, and slice assignment/deletion
- UISprite.cpp: Add markDirty() to scale/sprite_index/texture setters;
markCompositeDirty() to position setters
- UICircle.cpp: Add markDirty() to radius/fill_color/outline_color/outline;

All tutorial parts (1-13) used the old string-based key/action
comparison API removed in 6d5e99a. Every handle_keys function now
uses mcrfpy.Key.* and mcrfpy.InputState.PRESSED enums.
Additional fixes across all parts:
- Replace manual FOV computation with ColorLayer.draw_fov() which
handles FOV calculation and explored-state tracking in one call
- Replace old grid.add_layer("color") with ColorLayer() constructor
- Fix entity removal bug: entities.remove(index) -> remove(entity_ref)
- Remove manual exploration tracking (draw_fov handles it internally)
- Use tuple positions for compute_fov/is_in_fov: (x, y) not x, y
All 14 parts (0-13) tested and passing in headless mode.

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

files to use enum members instead of string comparisons. Also updates
grid.position -> grid.pos in files that had both types of changes.

Color had __hash__ but no __eq__/__ne__, violating the Python convention
that hashable objects must support equality comparison. Two Color objects
with identical RGBA values would not compare equal.
Now supports comparison with Color objects, tuples, and lists:
Color(255, 0, 0) == Color(255, 0, 0) # True
Color(255, 0, 0) == (255, 0, 0) # True
Color(255, 0, 0) != (0, 0, 0) # True

mcrfpy.Grid() now creates a GridView that internally owns a GridData (UIGrid).
The old UIGrid type is renamed to _GridData (internal). Attribute access on Grid
delegates to the underlying UIGrid via tp_getattro/tp_setattro, so all existing
Grid properties (grid_w, grid_h, entities, cells, layers, etc.) work transparently.
Key changes:
- GridView init has two modes: factory (Grid(grid_size=...)) and explicit view
(Grid(grid=existing_grid, ...)) for future multi-view support
- Entity.grid getter returns GridView wrapper via owning_view back-reference
- Entity.grid setter accepts GridView objects
- GridLayer set_grid handles GridView (extracts underlying UIGrid)
- UIDrawable::removeFromParent handles UIGRIDVIEW type correctly
- UIFrame children init accepts GridView objects
- Animation system supports GridView (center, zoom, shader.* properties)
- PythonObjectCache registration preserves subclass identity
- All 263 tests pass (100%)

Grid.__init__() now auto-creates a GridView that shares the Grid's
data via aliasing shared_ptr. This enables the Grid/GridView split:
- PyUIGridObject gains a `view` member (shared_ptr<UIGridView>)
- Grid.view property exposes the auto-created GridView (read-only)
- Rendering property setters (center_x/y, zoom, camera_rotation, x, y,
w, h) sync changes to the view automatically
- Grid still works as UIDrawable in scenes (no substitution) — backward
compatible with all existing code and subclasses
- GridView.grid returns the original Grid with identity preservation
- Explicit GridViews (created by user) are independent of Grid's own
rendering properties
Addresses #252. All 260 tests pass, no breaking changes.

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.

The Phase 3 fix for #266 removed UIEntity::self which prevented
tp_dealloc from ever running. However, this also allowed Python
subclass wrappers (GameEntity, ZoneExit, etc.) to be GC'd while
the C++ entity lived on in a grid. Later access via grid.entities
returned a base Entity wrapper, losing all subclass methods.
Fix: Add UIEntity::pyobject field that holds a strong reference to
the Python wrapper. Set in init(), cleared when the entity leaves
a grid (die(), set_grid(None), collection removal). This keeps
subclass identity alive while in a grid, but allows proper GC when
the entity is removed. Added releasePyIdentity() helper called at
all grid exit points.
Regression test exercises Liber Noster patterns: subclass hierarchy,
isinstance() checks, combat mixins, tooltip/send methods, GC
survival, die(), pop(), remove(), and stress test with 20 entities.

UniformCollection accessor methods checked the raw collection pointer
but never checked if the owning object was still alive. Changed owner
field from weak_ptr<UIDrawable> to weak_ptr<void> (type-erased) so
both UIDrawable and UIEntity owners can be tracked. Set owner in both
get_uniforms() paths. All accessors now check owner.lock() before
dereferencing the raw collection pointer.
