/**
 * Color utility class for managing colors in various formats. Provides a unified way to work
 * with colors across your PixiJS application.
 *
 * Features:
 * - Accepts multiple color formats (hex, RGB, HSL, etc.)
 * - Automatic format conversion
 * - Color manipulation methods
 * - Component access (r,g,b,a)
 * - Chainable operations
 * @example
 * ```js
 * import { Color } from 'pixi.js';
 *
 * new Color('red').toArray(); // [1, 0, 0, 1]
 * new Color(0xff0000).toArray(); // [1, 0, 0, 1]
 * new Color('ff0000').toArray(); // [1, 0, 0, 1]
 * new Color('#f00').toArray(); // [1, 0, 0, 1]
 * new Color('0xff0000ff').toArray(); // [1, 0, 0, 1]
 * new Color('#f00f').toArray(); // [1, 0, 0, 1]
 * new Color({ r: 255, g: 0, b: 0, a: 0.5 }).toArray(); // [1, 0, 0, 0.5]
 * new Color('rgb(255, 0, 0, 0.5)').toArray(); // [1, 0, 0, 0.5]
 * new Color([1, 1, 1]).toArray(); // [1, 1, 1, 1]
 * new Color([1, 0, 0, 0.5]).toArray(); // [1, 0, 0, 0.5]
 * new Color(new Float32Array([1, 0, 0, 0.5])).toArray(); // [1, 0, 0, 0.5]
 * new Color(new Uint8Array([255, 0, 0, 255])).toArray(); // [1, 0, 0, 1]
 * new Color(new Uint8ClampedArray([255, 0, 0, 255])).toArray(); // [1, 0, 0, 1]
 * new Color({ h: 0, s: 100, l: 50, a: 0.5 }).toArray(); // [1, 0, 0, 0.5]
 * new Color('hsl(0, 100%, 50%, 50%)').toArray(); // [1, 0, 0, 0.5]
 * new Color({ h: 0, s: 100, v: 100, a: 0.5 }).toArray(); // [1, 0, 0, 0.5]
 *
 * // Convert between formats
 * const color = new Color('red');
 * color.toHex();        // "#ff0000"
 * color.toRgbString();  // "rgb(255,0,0,1)"
 * color.toNumber();     // 0xff0000
 *
 * // Access components
 * color.red;    // 1
 * color.green;  // 0
 * color.blue;   // 0
 * color.alpha;  // 1
 *
 * // Chain operations
 * color
 *   .setAlpha(0.5)
 *   .multiply([0.5, 0.5, 0.5])
 *   .premultiply(0.8);
 * ```
 * @remarks
 * The Color class automatically normalizes all color values internally:
 * - RGB components are stored as floats between 0-1
 * - Alpha is always between 0-1
 * - Color operations clamp values to valid ranges
 * - Original input format is preserved when possible

 * The primary goal of the Shader class is to offer a unified interface compatible with both WebGL and WebGPU.

/**
 * The filter pipeline is responsible for applying filters scene items!
 *
 * KNOWN BUGS:
 * 1. Global bounds calculation is incorrect if it is used when flip flopping filters. The maths can be found below
 * eg: filters [noiseFilter, blurFilter] noiseFilter will calculate the global bounds incorrectly.
 *
 * 2. RenderGroups do not work with filters. This is because the renderGroup matrix is not currently taken into account.
 *
 * Implementation notes:
 * 1. Gotcha - nesting filters that require blending will not work correctly. This creates a chicken and egg problem
 * the complexity and performance required to do this is not worth it i feel.. but lets see if others agree!
 *
 * 2. Filters are designed to be changed on the fly, this is means that changing filter information each frame will
 * not trigger an instruction rebuild. If you are constantly turning a filter on and off.. its therefore better to set
 * enabled to true or false on the filter. Or setting an empty array.
 *
 * 3. Need to look at perhaps aliasing when flip flopping filters. Really we should only need to antialias the FIRST
 * Texture we render too. The rest can be non aliased. This might help performance.
 * Currently we flip flop with an antialiased texture if antialiasing is enabled on the filter.

 * The following happens under the hood when a filter is applied:

 * .4. Render the target to that texture
 * <br>
 * .5. Render that texture back to the main frame buffer as a quad using the filters program.

 * Some filters (such as blur) require multiple passes too which can result in an even bigger performance hit. So be careful!

 * using getStateKey for global state and getGraphicsStateKey for draw-specific settings. These keys are

/**
 * The RenderableGCSystem is responsible for cleaning up GPU resources that are no longer being used.
 *
 * When rendering objects like sprites, text, etc - GPU resources are created and managed by the renderer.
 * If these objects are no longer needed but not properly destroyed (via sprite.destroy()), their GPU resources
 * would normally leak. This system prevents that by automatically cleaning up unused GPU resources.
 *
 * Key features:
 * - Runs every 30 seconds by default to check for unused resources
 * - Cleans up resources not rendered for over 1 minute
 * - Works independently of rendering - will clean up even when not actively rendering
 * - When cleaned up resources are needed again, new GPU objects are quickly assigned from a pool
 * - Can be disabled with renderableGCActive:false for manual control
 *
 * Best practices:
 * - Always call destroy() explicitly when done with renderables (e.g. sprite.destroy())
 * - This system is a safety net, not a replacement for proper cleanup
 * - Adjust frequency and timeouts via options if needed
 * @example
 * ```js
 * // Sprite created but reference lost without destroy
 * let sprite = new Sprite(texture);
 *
 * // internally the renderer will assign a resource to the sprite
 * renderer.render(sprite);
 *
 * sprite = null; // Reference lost but GPU resources still exist
 *
 * // After 1 minute of not being rendered:
 * // - RenderableGC will clean up the sprite's GPU resources
 * // - JS garbage collector can then clean up the sprite itself

/**
 * The base class for a PixiJS Renderer. It contains the shared logic for all renderers.
 *
 * You should not use this class directly, but instead use {@link WebGLRenderer}
 * or {@link WebGPURenderer}.
 * Alternatively, you can also use {@link autoDetectRenderer} if you want us to
 * determine the best renderer for you.
 *
 * The renderer is composed of systems that manage specific tasks. The following systems are added by default
 * whenever you create a renderer:
 *
 *
 * | Generic Systems                      | Systems that manage functionality that all renderer types share               |
 * | ------------------------------------ | ----------------------------------------------------------------------------- |
 * | {@link ViewSystem}              | This manages the main view of the renderer usually a Canvas              |
 * | {@link BackgroundSystem}        | This manages the main views background color and alpha                   |
 * | {@link EventSystem}           | This manages UI events.                                                       |
 * | {@link AccessibilitySystem} | This manages accessibility features. Requires `import 'pixi.js/accessibility'`|
 *
 * | Core Systems                   | Provide an optimised, easy to use API to work with WebGL/WebGPU               |
 * | ------------------------------------ | ----------------------------------------------------------------------------- |
 * | {@link GlobalUniformSystem} | This manages shaders, programs that run on the GPU to calculate 'em pixels.   |
 * | {@link TextureGCSystem}     | This will automatically remove textures from the GPU if they are not used.    |
 *
 * | PixiJS High-Level Systems            | Set of specific systems designed to work with PixiJS objects                  |
 * | ------------------------------------ | ----------------------------------------------------------------------------- |
 * | {@link HelloSystem}               | Says hello, buy printing out the pixi version into the console log (along with the renderer type)       |
 * | {@link GenerateTextureSystem} | This adds the ability to generate textures from any Container       |
 * | {@link FilterSystem}          | This manages the filtering pipeline for post-processing effects.             |
 * | {@link PrepareSystem}               | This manages uploading assets to the GPU. Requires `import 'pixi.js/prepare'`|
 * | {@link ExtractSystem}               | This extracts image data from display objects.                               |
 *
 * The breadth of the API surface provided by the renderer is contained within these systems.

 * A wrapper for a WebGPU/WebGL Buffer.
 * In PixiJS, the Buffer class is used to manage the data that is sent to the GPU rendering pipeline.
 * It abstracts away the underlying GPU buffer and provides an interface for uploading typed arrays or other data to the GPU,
 * They are used in the following places:
 * <br><br>
 * .1. {@link Geometry} as attribute data or index data for geometry
 * <br>
 * .2. {@link UniformGroup} as an underlying buffer for uniform data
 * <br>
 * .3. {@link BufferResource} as an underlying part of a buffer used directly by the GPU program
 * <br>
 *
 * It is important to note that you must provide a usage type when creating a buffer. This is because
 * the underlying GPU buffer needs to know how it will be used. For example, if you are creating a buffer
 * to hold vertex data, you would use `BufferUsage.VERTEX`. This will tell the GPU that this buffer will be
 * used as a vertex buffer. This is important because it will affect how you can use the buffer.
 *
 * Buffers are updated by calling the {@link Buffer.update} method. This immediately updates the buffer on the GPU.
 * Be mindful of calling this more often than you need to. It is recommended to update buffers only when needed.
 *
 * In WebGPU, a GPU buffer cannot resized. This limitation is abstracted away, but know that resizing a buffer means
 * creating a brand new one and destroying the old, so it is best to limit this if possible.
 * @example
 *
 * const buffer = new Buffer({
 *     data: new Float32Array([1, 2, 3, 4]),
 *     usage: BufferUsage.VERTEX,

/**
 * The RenderLayer API provides a way to control the rendering order of objects independently
 * of their logical parent-child relationships in the scene graph.
 * This allows developers to decouple how objects are transformed
 * (via their logical parent) from how they are rendered on the screen.
 *
 * ### Key Concepts
 *
 * #### RenderLayers Control Rendering Order:
 * - RenderLayers define where in the render stack objects are drawn,
 * but they do not affect an object's transformations (e.g., position, scale, rotation) or logical hierarchy.
 * - RenderLayers can be added anywhere in the scene graph.
 *
 * #### Logical Parenting Remains Unchanged:
 * - Objects still have a logical parent for transformations via addChild.
 * - Assigning an object to a layer does not reparent it.
 *
 * #### Explicit Control:
 * - Developers assign objects to layers using renderLayer.add and remove them using renderLayer.remove.
 * ---
 * ### API Details
 *
 * #### 1. Creating a RenderLayer
 * A RenderLayer is a lightweight object responsible for controlling render order.
 * It has no children or transformations of its own
 * but can be inserted anywhere in the scene graph to define its render position.
 * ```js
 * const layer = new RenderLayer();
 * app.stage.addChild(layer); // Insert the layer into the scene graph
 * ```
 *
 * #### 2. Adding Objects to a Layer
 * Use renderLayer.add to assign an object to a layer.
 * This overrides the object's default render order defined by its logical parent.
 * ```js
 * const rect = new Graphics();
 * container.addChild(rect);    // Add to logical parent
 * layer.attach(rect);      // Control render order via the layer
 * ```
 *
 * #### 3. Removing Objects from a Layer
 * To stop an object from being rendered in the layer, use remove.
 * ```js
 * layer.remove(rect); // Stop rendering rect via the layer
 * ```
 * When an object is removed from its logical parent (removeChild), it is automatically removed from the layer.
 *
 * #### 4. Re-Adding Objects to Layers
 * If an object is re-added to a logical parent, it does not automatically reassign itself to the layer.
 * Developers must explicitly reassign it.
 * ```js
 * container.addChild(rect);    // Logical parent
 * layer.attach(rect);      // Explicitly reassign to the layer
 * ```
 *
 * #### 5. Layer Position in Scene Graph
 * A layer's position in the scene graph determines its render priority relative to other layers and objects.
 * Layers can be inserted anywhere in the scene graph.
 * ```js
 * const backgroundLayer = new RenderLayer();
 * const uiLayer = new RenderLayer();
 *
 * app.stage.addChild(backgroundLayer);
 * app.stage.addChild(world);
 * app.stage.addChild(uiLayer);
 * ```
 * This is a new API and therefore considered experimental at this stage.
 * While the core is pretty robust, there are still a few tricky issues we need to tackle.
 * However, even with the known issues below, we believe this API is incredibly useful!
 *
 * Known issues:
 *  - Interaction may not work as expected since hit testing does not account for the visual render order created by layers.
 *    For example, if an object is visually moved to the front via a layer, hit testing will still use its original position.
 *  - RenderLayers and their children must all belong to the same renderGroup to work correctly.
 *  - Filters on ancestor containers do not apply to children attached to a RenderLayer.
 *    This is because render layer children are rendered outside their parent's filter scope
 *    (filters capture children into a texture via push/pop, but render layer children skip
 *    their parent's collection and render at the layer's position instead).

 *         space. The default value of the pivot is the origin (0,0). If the top-left corner of your display object
 *         is (0,0) in its local space, then the position will be its top-left corner in the parent's local space.
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[scale]{@link Container#scale}</td>
 *       <td>
 *         Scaling. This will stretch (or compress) the display object's projection. The scale factors are along the
 *         local coordinate axes. In other words, the display object is scaled before rotated or skewed. The center
 *         of scaling is the [pivot]{@link Container#pivot}.
 *       </td>

 *     <tr>
 *       <td>[rotation]{@link Container#rotation}</td>
 *       <td>
 *          Rotation. This will rotate the display object's projection by this angle (in radians).

 *         <p>Skewing. This can be used to deform a rectangular display object into a parallelogram.</p>
 *         <p>
 *         In PixiJS, skew has a slightly different behaviour than the conventional meaning. It can be
 *         thought of the net rotation applied to the coordinate axes (separately). For example, if "skew.x" is
 *         ⍺ and "skew.y" is β, then the line x = 0 will be rotated by ⍺ (y = -x*cot⍺) and the line y = 0 will be
 *         rotated by β (y = x*tanβ). A line y = x*tanϴ (i.e. a line at angle ϴ to the x-axis in local-space) will
 *         be rotated by an angle between ⍺ and β.
 *         </p>
 *         <p>
 *         It can be observed that if skew is applied equally to both axes, then it will be equivalent to applying
 *         a rotation. Indeed, if "skew.x" = -ϴ and "skew.y" = ϴ, it will produce an equivalent of "rotation" = ϴ.
 *         </p>
 *         <p>
 *         Another quite interesting observation is that "skew.x", "skew.y", rotation are commutative operations. Indeed,
 *         because rotation is essentially a careful combination of the two.
 *         </p>

 * <summary>Alpha</summary>
 *
 * This alpha sets a display object's **relative opacity** w.r.t its parent. For example, if the alpha of a display
 * object is 0.5 and its parent's alpha is 0.5, then it will be rendered with 25% opacity (assuming alpha is not
 * applied on any ancestor further up the chain).
 * </details>
 *
 * <details id="visible">
 * <summary>Renderable vs Visible</summary>
 *
 * The `renderable` and `visible` properties can be used to prevent a display object from being rendered to the
 * screen. However, there is a subtle difference between the two. When using `renderable`, the transforms  of the display
 * object (and its children subtree) will continue to be calculated. When using `visible`, the transforms will not
 * be calculated.
 * ```ts
 * import { BlurFilter, Container, Graphics, Sprite } from 'pixi.js';
 *
 * const container = new Container();
 * const sprite = Sprite.from('https://s3-us-west-2.amazonaws.com/s.cdpn.io/693612/IaUrttj.png');
 *
 * sprite.width = 512;
 * sprite.height = 512;
 *
 * // Adds a sprite as a child to this container. As a result, the sprite will be rendered whenever the container
 * // is rendered.
 * container.addChild(sprite);
 *
 * // Blurs whatever is rendered by the container
 * container.filters = [new BlurFilter()];
 *
 * // Only the contents within a circle at the center should be rendered onto the screen.
 * container.mask = new Graphics()
 *     .beginFill(0xffffff)
 *     .drawCircle(sprite.width / 2, sprite.height / 2, Math.min(sprite.width, sprite.height) / 2)
 *     .endFill();
 * ```
 *
 * </details>
 *
 * <details id="renderGroup">
 * <summary>RenderGroup</summary>
 *
 * In PixiJS v8, containers can be set to operate in 'render group mode',
 * transforming them into entities akin to a stage in traditional rendering paradigms.
 * A render group is a root renderable entity, similar to a container,
 * but it's rendered in a separate pass with its own unique set of rendering instructions.
 * This approach enhances rendering efficiency and organization, particularly in complex scenes.
 *
 * You can enable render group mode on any container using container.enableRenderGroup()
 * or by initializing a new container with the render group property set to true (new Container({isRenderGroup: true})).
 *  The method you choose depends on your specific use case and setup requirements.
 *
 * An important aspect of PixiJS’s rendering process is the automatic treatment of rendered scenes as render groups.
 * This conversion streamlines the rendering process, but understanding when and how this happens is crucial
 * to fully leverage its benefits.
 *
 * One of the key advantages of using render groups is the performance efficiency in moving them. Since transformations
 *  are applied at the GPU level, moving a render group, even one with complex and numerous children,
 * doesn't require recalculating the rendering instructions or performing transformations on each child.
 * This makes operations like panning a large game world incredibly efficient.
 *
 * However, it's crucial to note that render groups do not batch together.
 * This means that turning every container into a render group could actually slow things down,
 * as each render group is processed separately. It's best to use render groups judiciously, at a broader level,
 * rather than on a per-child basis.
 * This approach ensures you get the performance benefits without overburdening the rendering process.
 *
 * RenderGroups maintain their own set of rendering instructions,
 * ensuring that changes or updates within a render group don't affect the rendering
 * instructions of its parent or other render groups.
 *  This isolation ensures more stable and predictable rendering behavior.
 *
 * Additionally, renderGroups can be nested, allowing for powerful options in organizing different aspects of your scene.
 * This feature is particularly beneficial for separating complex game graphics from UI elements,
 * enabling intricate and efficient scene management in complex applications.
 *
 * This means that Containers have 3 levels of matrix to be mindful of:
 *
 * 1. localTransform, this is the transform of the container based on its own properties
 * 2. groupTransform, this it the transform of the container relative to the renderGroup it belongs too
 * 3. worldTransform, this is the transform of the container relative to the Scene being rendered

	 * Enable interaction events for the Container. Touch, pointer and mouse events are supported.
	 * @example
	 * ```ts
	 * const sprite = new Sprite(texture);
	 *
	 * // Enable standard interaction (like buttons)
	 * sprite.eventMode = 'static';
	 * sprite.on('pointerdown', () => console.log('clicked!'));

	 *
	 * // Disable all interaction
	 * sprite.eventMode = 'none';
	 *
	 * // Only allow child interactions
	 * sprite.eventMode = 'passive';
	 * ```
	 *
	 * Available modes:
	 *
	 * - `'none'`: Ignores all interaction events, even on its children. Best for pure visuals.
	 * - `'passive'`: **(default)** Does not emit events and ignores hit testing on itself and non-interactive
	 * children. Interactive children will still emit events.
	 * - `'auto'`: Does not emit events but is hit tested if parent is interactive. Same as `interactive = false` in v7.
	 * - `'static'`: Emit events and is hit tested. Same as `interactive = true` in v7. Best for buttons/UI.
	 * - `'dynamic'`: Like static but also receives synthetic events when pointer is idle. Best for moving objects.
	 *
	 * Performance tips:
	 * - Use `'none'` for pure visual elements
	 * - Use `'passive'` for containers with some interactive children
	 * - Use `'static'` for standard UI elements
	 * - Use `'dynamic'` only when needed for moving/animated elements

/**
 * A perspective mesh that allows you to draw a 2d plane with perspective. Where ever you move the corners
 * the texture will be projected to look like it is in 3d space. Great for mapping a 2D mesh into a 3D scene.
 *
 * The calculations is done at the uv level. This means that the more vertices you have the more smooth
 * the perspective will be. If you have a low amount of vertices you may see the texture stretch. Too many vertices
 * could be slower. It is a balance between performance and quality! We leave that to you to decide.

 * The ParticleContainer class is a highly optimized container that can render 1000s or particles at great speed.
 *
 * A ParticleContainer is specialized in that it can only contain and render particles. Particles are
 * lightweight objects that use minimal memory, which helps boost performance.
 *
 * It can render particles EXTREMELY fast!
 *
 * The tradeoff of using a ParticleContainer is that most advanced functionality is unavailable. Particles are simple
 * and cannot have children, filters, masks, etc. They possess only the basic properties: position, scale, rotation,
 * and color.
 *
 * All particles must share the same texture source (using something like a sprite sheet works well here).
 *
 * When creating a ParticleContainer, a developer can specify which of these properties are static and which are dynamic.
 * - Static properties are only updated when you add or remove a child, or when the `update` function is called.
 * - Dynamic properties are updated every frame.
 *
 * It is up to the developer to specify which properties are static and which are dynamic. Generally, the more static
 * properties you have (i.e., those that do not change per frame), the faster the rendering.
 *
 * If the developer modifies the children order or any static properties of the particle, they must call the `update` method.
 *
 * By default, only the `position` property is set to dynamic, which makes rendering very fast!
 *
 * Developers can also provide a custom shader to the particle container, allowing them to render particles in a custom way.
 *
 * To help with performance, the particle containers bounds are not calculated.
 * It's up to the developer to set the boundsArea property.
 *
 * It's extremely easy to use. Below is an example of rendering thousands of sprites at lightning speed.
 *

/**
 * A BitmapText object creates text using pre-rendered bitmap fonts.
 * It supports both loaded bitmap fonts (XML/FNT) and dynamically generated ones.
 *
 * To split a line you can use '\n' in your text string, or use the `wordWrap` and
 * `wordWrapWidth` style properties.
 *
 * Key Features:
 * - High-performance text rendering using pre-generated textures
 * - Support for both pre-loaded and dynamic bitmap fonts
 * - Compatible with MSDF/SDF fonts for crisp scaling
 * - Automatic font reuse and optimization
 *
 * Performance Benefits:
 * - Faster rendering compared to Canvas/HTML text
 * - Lower memory usage for repeated characters
 * - More efficient text changes
 * - Better batching capabilities
 *
 * Limitations:
 * - Full character set support is impractical due to the number of chars (mainly affects CJK languages)
 * - Initial font generation/loading overhead
 * - Less flexible styling compared to Canvas/HTML text
 * @example
 * ```ts
 * import { BitmapText, BitmapFont } from 'pixi.js';
 *
 * // Dynamic font generation
 * const dynamicText = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *         fontFamily: 'Arial',
 *         fontSize: 24,
 *         fill: 0xff1010,
 *         align: 'center',
 *     }
 * });
 *
 * // Pre-installed font usage
 * BitmapFont.install({
 *    name: 'myFont',
 *    style: {
 *        fontFamily: 'Arial',
 *    }
 * });
 *
 * const preinstalledText = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *        fontFamily: 'myFont',
 *        fontSize: 24,
 *        fill: 0xff1010,
 *        align: 'center',
 *     }
 * });
 *
 * // Load and use external bitmap font, if the font supports MSDF/SDF then it will be used
 * const font = await Assets.load('fonts/myFont.fnt');
 *
 * const loadedFontText = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *        fontFamily: 'myLoadedFont', // Name from .fnt file
 *        fontSize: 24,
 *        fill: 0xff1010,
 *        align: 'center',
 *     }
 * });
 *
 * // Multiline text with word wrap
 * const wrappedText = new BitmapText({
 *     text: 'This is a long text that will wrap automatically',
 *     style: {
 *         fontFamily: 'Arial',
 *         fontSize: 24,
 *         wordWrap: true,
 *         wordWrapWidth: 200,
 *     }
 * });
 * ```
 *
 * Font Types:
 * 1. Pre-loaded Bitmap Fonts:
 *    - Load via Asset Manager (XML/FNT formats)
 *    - Support for MSDF/SDF fonts
 *    - Create using tools like https://msdf-bmfont.donmccurdy.com/
 *
 * 2. Dynamic Bitmap Fonts:
 *    - Generated at runtime from system fonts
 *    - Automatic font reuse and optimization
 *    - Smart scaling for similar font sizes
 *
 * Font Management:
 * - Automatic font generation when needed
 * - Manual pre-installation via `BitmapFont.install`
 * - Smart font reuse to optimize memory
 * - Scale existing fonts instead of generating new ones when possible

 * ```ts
 * const text = new SplitText({
 *   text: "Hello World",
 *   style: { fontSize: 24 },
 *   // Origin points for transformations (0-1 range)
 *   lineAnchor: 0.5,  // Center of each line

 *   charAnchor: { x: 0.5, y: 1 },  // Bottom-center of each character
 *   autoSplit: true  // Auto-update segments on text/style changes
 * });
 * ```
 *
 * Features:
 * - Hierarchical text splitting (lines → words → characters)
 * - Independent transformation origins for each segment level
 * - Automatic or manual segment updates
 * - Support for both canvas text and bitmap text
 * @example Animation Example
 * ```ts
 * // Character fade-in sequence
 * text.chars.forEach((char, i) => {
 *   gsap.from(char, {
 *     alpha: 0,
 *     delay: i * 0.1

 *     yoyo: true,
 *     repeat: -1,
 *     delay: i * 0.2
 *   });
 * });
 *
 * // Line slide-in effect
 * text.lines.forEach((line, i) => {
 *   gsap.from(line, {
 *     x: -200,
 *     delay: i * 0.3
 *   });
 * });
 * ```
 *
 * Configuration Options:
 * - `text`: The string to render and segment
 * - `style`: TextStyle instance or configuration object
 * - `autoSplit`: Automatically update segments on changes (default: true)
 * - `lineAnchor`: Transform origin for lines (default: 0)
 * - `wordAnchor`: Transform origin for words (default: 0)
 * - `charAnchor`: Transform origin for characters (default: 0)
 *
 * > [!NOTE] Anchor points are normalized (0-1):
 * > - 0,0: Top-left
 * > - 0.5,0.5: Center
 * > - 1,1: Bottom-right

 * @experimental
 * A container that splits text into individually manipulatable segments (lines, words, and characters)

 * Converts each segment into a separate Text object.
 * @example Basic Usage
 * ```ts
 * const text = new SplitText({
 *   text: "Hello World",
 *   style: { fontSize: 24 },
 *   // Origin points for transformations (0-1 range)
 *   lineAnchor: 0.5,  // Center of each line

 *   charAnchor: { x: 0.5, y: 1 },  // Bottom-center of each character
 *   autoSplit: true  // Auto-update segments on text/style changes
 * });
 * ```
 *
 * Features:
 * - Hierarchical text segmentation (lines → words → characters)
 * - Independent transformation origins for each segment level
 * - Automatic or manual segment updates
 * @example Animation Example
 * ```ts
 * // Character fade-in sequence
 * text.chars.forEach((char, i) => {
 *   gsap.from(char, {
 *     alpha: 0,
 *     delay: i * 0.1
 *   });
 * });
 *
 * // Word scale animation
 * text.words.forEach((word, i) => {
 *   gsap.to(word.scale, {
 *     x: 1.2, y: 1.2,
 *     yoyo: true,
 *     repeat: -1,
 *     delay: i * 0.2
 *   });
 * });
 *
 * // Line slide-in effect
 * text.lines.forEach((line, i) => {
 *   gsap.from(line, {
 *     x: -200,
 *     delay: i * 0.3
 *   });
 * });
 * ```
 *
 * Configuration Options:
 * - `text`: The string to render and segment
 * - `style`: TextStyle instance or configuration object
 * - `autoSplit`: Automatically update segments on changes (default: true)
 * - `lineAnchor`: Transform origin for lines (default: 0)
 * - `wordAnchor`: Transform origin for words (default: 0)
 * - `charAnchor`: Transform origin for characters (default: 0)
 *
 * > [!NOTE] Anchor points are normalized (0-1):
 * > - 0,0: Top-left
 * > - 0.5,0.5: Center
 * > - 1,1: Bottom-right
 *
 * > [!WARNING] Limitations

/**
 * @experimental
 * A container that splits text into individually manipulatable segments (lines, words, and characters)
 * for advanced text effects and animations.
 * Converts each segment into a separate BitmapText object.
 * @example Basic Usage
 * ```ts
 * const text = new SplitBitmapText({
 *   text: "Hello World",
 *   style: { fontSize: 24 },
 *   // Origin points for transformations (0-1 range)
 *   lineAnchor: 0.5,  // Center of each line
 *   wordAnchor: { x: 0, y: 0.5 },  // Left-center of each word
 *   charAnchor: { x: 0.5, y: 1 },  // Bottom-center of each character
 *   autoSplit: true  // Auto-update segments on text/style changes
 * });
 * ```
 *
 * Features:
 * - Hierarchical text segmentation (lines → words → characters)
 * - Independent transformation origins for each segment level
 * - Automatic or manual segment updates
 * @example Animation Example
 * ```ts
 * // Character fade-in sequence
 * text.chars.forEach((char, i) => {
 *   gsap.from(char, {
 *     alpha: 0,
 *     delay: i * 0.1
 *   });
 * });
 *
 * // Word scale animation
 * text.words.forEach((word, i) => {
 *   gsap.to(word.scale, {
 *     x: 1.2, y: 1.2,
 *     yoyo: true,
 *     repeat: -1,
 *     delay: i * 0.2
 *   });
 * });
 *
 * // Line slide-in effect
 * text.lines.forEach((line, i) => {
 *   gsap.from(line, {
 *     x: -200,
 *     delay: i * 0.3
 *   });
 * });
 * ```
 *
 * Configuration Options:
 * - `text`: The string to render and segment
 * - `style`: TextStyle instance or configuration object
 * - `autoSplit`: Automatically update segments on changes (default: true)
 * - `lineAnchor`: Transform origin for lines (default: 0)
 * - `wordAnchor`: Transform origin for words (default: 0)
 * - `charAnchor`: Transform origin for characters (default: 0)
 *
 * > [!NOTE] Anchor points are normalized (0-1):
 * > - 0,0: Top-left
 * > - 0.5,0.5: Center
 * > - 1,1: Bottom-right
 *
 * > [!WARNING] Limitations
 * > - Character spacing may differ slightly from standard text due to browser
 * >   kerning being lost when characters are separated

/**
 * Utility class for maintaining reference to a collection

 *
 * To access a sprite sheet from your code you may pass its JSON data file to Pixi's loader:
 *
 * ```js
 * import { Assets } from 'pixi.js';
 *
 * const sheet = await Assets.load('images/spritesheet.json');
 * ```
 *
 * Alternately, you may circumvent the loader by instantiating the Spritesheet directly:
 *
 * ```js
 * import { Spritesheet } from 'pixi.js';
 *
 * const sheet = new Spritesheet(texture, spritesheetData);
 * await sheet.parse();
 * console.log('Spritesheet ready to use!');
 * ```
 *
 * With the `sheet.textures` you can create Sprite objects, and `sheet.animations` can be used to create an AnimatedSprite.
 *
 * Here's an example of a sprite sheet JSON data file:
 * ```json
 * {
 *     "frames": {
 *         "enemy1.png":
 *         {
 *             "frame": {"x":103,"y":1,"w":32,"h":32},
 *             "spriteSourceSize": {"x":0,"y":0,"w":32,"h":32},
 *             "sourceSize": {"w":32,"h":32},
 *             "anchor": {"x":0.5,"y":0.5}
 *         },

 *         "scale": "1"
 *     }
 * }
 * ```
 * Sprite sheets can be packed using tools like {@link https://codeandweb.com/texturepacker|TexturePacker},
 * {@link https://renderhjs.net/shoebox/|Shoebox} or {@link https://github.com/krzysztof-o/spritesheet.js|Spritesheet.js}.
 * Default anchor points (see {@link Texture#defaultAnchor}), default 9-slice borders
 * (see {@link Texture#defaultBorders}) and grouping of animation sprites are currently only
 * supported by TexturePacker.
 *
 * Alternative ways for loading spritesheet image if you need more control:
 *
 * ```js
 * import { Assets } from 'pixi.js';
 *
 * const sheetTexture = await Assets.load('images/spritesheet.png');
 * Assets.add({
 *     alias: 'atlas',
