/**
 * Container is a general-purpose display object that holds children. It also adds built-in support for advanced
 * rendering features like masking and filtering.
 *
 * It is the base class of all display objects that act as a container for other objects, including Graphics
 * and Sprite.
 *
 * <details id="transforms">
 *
 * <summary>Transforms</summary>
 *
 * The [transform]{@link scene.Container#transform} of a display object describes the projection from its
 * local coordinate space to its parent's local coordinate space. The following properties are derived
 * from the transform:
 *
 * <table>
 *   <thead>
 *     <tr>
 *       <th>Property</th>
 *       <th>Description</th>
 *     </tr>
 *   </thead>
 *   <tbody>
 *     <tr>
 *       <td>[pivot]{@link scene.Container#pivot}</td>
 *       <td>
 *         Invariant under rotation, scaling, and skewing. The projection of into the parent's space of the pivot
 *         is equal to position, regardless of the other three transformations. In other words, It is the center of
 *         rotation, scaling, and skewing.
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[position]{@link scene.Container#position}</td>
 *       <td>
 *         Translation. This is the position of the [pivot]{@link scene.Container#pivot} in the parent's local
 *         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 scene.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 scene.Container#pivot}.
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[rotation]{@link scene.Container#rotation}</td>
 *       <td>
 *          Rotation. This will rotate the display object's projection by this angle (in radians).
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[skew]{@link scene.Container#skew}</td>
 *       <td>
 *         <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>
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[angle]{@link scene.Container#angle}</td>
 *       <td>Rotation. This is an alias for [rotation]{@link scene.Container#rotation}, but in degrees.</td>
 *     </tr>

 *         the "requested" width by the local bounding box width. It is indirectly an abstraction over scale.x, and there
 *         is no concept of user-defined width.

 *     </tr>
 *   </tbody>
 * </table>
 * </details>
 *
 * <details id="alpha">
 * <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

 * 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({

 * <b>Attributes</b>: These are essentially arrays that define properties of the vertices like position, color,

 * The Shader class is an integral part of the PixiJS graphics pipeline.

 * The shader incorporates a {@link GlProgram} for WebGL or a {@link GpuProgram} for WebGPU,
 * instructing the respective technology on how to render the geometry.
 *
 * The primary goal of the Shader class is to offer a unified interface compatible with both WebGL and WebGPU.
 * When constructing a shader, you need to provide both a WebGL program and a WebGPU program due to the distinctions
 * between the two rendering engines. If only one is provided, the shader won't function with the omitted renderer.
 *
 * Both WebGL and WebGPU utilize the same resource object when passed into the shader.
 * Post-creation, the shader's interface remains consistent across both WebGL and WebGPU.
 * The sole distinction lies in whether a glProgram or a gpuProgram is employed.
 *

 *  - TextureSampler {@link TextureStyle}

 * A system that creates and manages the GPU pipelines.

 * keys that represent the state of the graphics settings and the specific requirements of the
 * item being rendered. By caching these pipelines, subsequent draw calls with identical configurations
 * can reuse existing pipelines instead of generating new ones.
 *
 * State Management: The system differentiates between "global" state properties (like color masks
 * and stencil masks, which do not change frequently) and properties that may vary between draw calls
 * (such as geometry, shaders, and blend modes). Unique keys are generated for both these categories
 * using getStateKey for global state and getGraphicsStateKey for draw-specific settings. These keys are
 * then then used to caching the pipe. The next time we need a pipe we can check
 * the cache by first looking at the state cache and then the pipe cache.

 *
 * 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.

 * | {@link rendering.GlRenderTargetSystem}      | This manages what we render too. For example the screen, or another texture   |

/**
 * A BitmapText Object will create a line or multiple lines of text.
 *
 * To split a line you can use '\n' in your text string, or, on the `style` object,
 * change its `wordWrap` property to true and and give the `wordWrapWidth` property a value.
 *
 * The text is created using a bitmap font (a sprite sheet of characters).
 *
 * The primary advantage of this render mode over `text` is that all of your textures are pre-generated and loaded,
 * meaning that rendering is fast, and changing text is much faster than Text.
 *
 * The primary disadvantage is that supporting character sets other than latin, such as CJK languages,
 * may be impractical due to the number of characters.
 *
 * <b>Pre-loaded BitmapFonts:</b>
 *
 *
 * PixiJS enables the loading of BitmapFonts through its Asset Manager, supporting both XML and FNT formats.
 * Additionally, PixiJS is compatible with MSDF (Multi-channel Signed Distance Field) and SDF (Signed Distance Field) fonts.
 * These advanced font types allow for scaling without quality degradation and must be created with specific tools,
 * such as the one available at https://msdf-bmfont.donmccurdy.com/.
 *
 * <b>Dynamically Generated BitmapFonts:</b>
 *
 *
 * PixiJS also offers the capability to generate BitmapFonts dynamically. This means that fonts are created in real-time
 * based on specified styles, eliminating the need for pre-loading. This process is initiated simply by assigning a style
 * to a BitmapText object, which then automatically generates the required font.
 *
 * However, dynamically generating a large number of fonts may lead to significant memory use. To prevent this,
 * PixiJS smartly attempts to reuse fonts that closely match the desired style parameters. For instance, if a text style
 * requires a font size of 80 but a similar font of size 100 has already been generated, PixiJS will scale the existing
 * font to fit the new requirement, rather than creating a new font from scratch.
 *
 * For those who prefer to manage BitmapFonts manually, PixiJS provides the BitmapFont.install method. This method
 * allows for the pre-generation and preparation of fonts, making them readily available for use by specifying the
 * fontFamily in your text styling.
 *
 * This approach ensures efficient font management within PixiJS, balancing between dynamic generation for flexibility
 * and manual management for optimized performance.
 * @example
 * import { BitmapText, BitmapFont } from 'pixi.js';
 *
 * // generate a dynamic font behind the scenes:
 * const text = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *         fontFamily: 'Arial',
 *         fontSize: 24,
 *         fill: 0xff1010,
 *         align: 'center',
 *     }
 * });
 *
 * // pre install
 * BitmapFont.install({
 *    name: 'myFont',
 *    style:{
 *        fontFamily: 'Arial',
 *    }
 * })
 *
 * // new bitmap text with preinstalled font
 * const text = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *        fontFamily: 'myFont',
 *        fontSize: 24,
 *        fill: 0xff1010,
 *        align: 'center',
 *     }
 * }
 *
 * // load a font from an xml file
 * const font = await Assets.load('path/to/myLoadedFont.fnt');
 *
 * // new bitmap text with loaded font
 * const text = new BitmapText({
 *     text: 'Hello Pixi!',
 *     style: {
 *        fontFamily: 'myLoadedFont', // the name of the font in the fnt file
 *        fontSize: 24,

 *
 * The primary disadvantages are:

 * `html` uses SVG/DOM to render text and not Context2D's fillText like `text`.
 *
 *   - Performance and memory usage is on-par with `text` (that is to say, slow and heavy)

/**
 * A one stop shop for all Pixi resource management!
 * Super modern and easy to use, with enough flexibility to customize and do what you need!
 * @namespace assets
 *
 * Use the singleton class [Assets]{@link assets.Assets} to easily load and manage all your assets.
 *
 * ```typescript
 * import { Assets, Texture } from 'pixi.js';
 *
 * const bunnyTexture = await Assets.load<Texture>('bunny.png');
 * const sprite = new Sprite(bunnyTexture);
 * ```
 *
 * Check out the sections below for more information on how to deal with assets.
 *
 * <details id="assets-loading">
 *
 * <summary>Asset Loading</summary>
 *
 * Do not be afraid to load things multiple times - under the hood, it will **NEVER** load anything more than once.
 *
 * *For example:*
 *
 * ```js
 * import { Assets } from 'pixi.js';
 *
 * promise1 = Assets.load('bunny.png')
 * promise2 = Assets.load('bunny.png')
 *
 * // promise1 === promise2
 * ```
 *
 * Here both promises will be the same. Once resolved... Forever resolved! It makes for really easy resource management!
 *
 * Out of the box Pixi supports the following files:
 * - Textures (**_avif_**, **_webp_**, **_png_**, **_jpg_**, **_gif_**, **_svg_**) via {@link assets.loadTextures}, {@link assets.loadSvg}
 * - Video Textures (**_mp4_**, **_m4v_**, **_webm_**, **_ogg_**, **_ogv_**, **_h264_**, **_avi_**, **_mov_**) via {@link assets.loadVideoTextures}
 * - Sprite sheets (**_json_**) via {@link assets.spritesheetAsset}
 * - Bitmap fonts (**_xml_**, **_fnt_**, **_txt_**) via {@link assets.loadBitmapFont}
 * - Web fonts (**_ttf_**, **_woff_**, **_woff2_**) via {@link assets.loadWebFont}
 * - JSON files (**_json_**) via {@link assets.loadJson}
 * - Text Files (**_txt_**) via {@link assets.loadTxt}
 * <br/>
 * More types can be added fairly easily by creating additional {@link assets.LoaderParser LoaderParsers}.
 * </details>
 *
 * <details id="textures">
 *
 * <summary>Textures</summary>
 *
 * - Textures are loaded as ImageBitmap on a worker thread where possible. Leading to much less janky load + parse times.
 * - By default, we will prefer to load AVIF and WebP image files if you specify them.
 * But if the browser doesn't support AVIF or WebP we will fall back to png and jpg.
 * - Textures can also be accessed via `Texture.from()` (see {@link core.from|Texture.from})
 * and now use this asset manager under the hood!
 * - Don't worry if you set preferences for textures that don't exist
 * (for example you prefer 2x resolutions images but only 1x is available for that texture,
 * the Assets manager will pick that up as a fallback automatically)
 *
 * #### Sprite sheets
 * - It's hard to know what resolution a sprite sheet is without loading it first, to address this
 * there is a naming convention we have added that will let Pixi understand the image format and resolution
 * of the spritesheet via its file name: `my-spritesheet{resolution}.{imageFormat}.json`
 * <br><br>For example:
 *   - `my-spritesheet@2x.webp.json`* // 2x resolution, WebP sprite sheet*
 *   - `my-spritesheet@0.5x.png.json`* // 0.5x resolution, png sprite sheet*
 * - This is optional! You can just load a sprite sheet as normal.
 * This is only useful if you have a bunch of different res / formatted spritesheets.
 * </details>
 *
 * <details id="fonts">
 *
 * <summary>Fonts</summary>
 *
 * Web fonts will be loaded with all weights.
 * It is possible to load only specific weights by doing the following:
 *
 * ```js
 * import { Assets } from 'pixi.js';
 *
 * // Load specific weights..
 * await Assets.load({
 *     data: {
 *         weights: ['normal'], // Only loads the weight
 *     },
 *     src: `outfit.woff2`,
 * });
 *
 * // Load everything...
 * await Assets.load(`outfit.woff2`);
 * ```
 * </details>
 *
 * <details id="background-loading">
 *
 * <summary>Background Loading</summary>
 *
 * Background loading will load stuff for you passively behind the scenes. To minimize jank,
 * it will only load one asset at a time. As soon as a developer calls `Assets.load(...)` the
 * background loader is paused and requested assets are loaded as a priority.
 * Don't worry if something is in there that's already loaded, it will just get skipped!
 *
 * You still need to call `Assets.load(...)` to get an asset that has been loaded in the background.
 * It's just that this promise will resolve instantly if the asset
 * has already been loaded.
 * </details>
 *
 * <details id="manifests-and-bundles">
 *
 * <summary>Manifest and Bundles</summary>
 *
 * - {@link assets.AssetsManifest Manifest} is a descriptor that contains a list of all assets and their properties.
 * - {@link assets.AssetsBundle Bundles} are a way to group assets together.
 *
 * ```js
 * import { Assets } from 'pixi.js';

 * The global Assets class, it's a singleton so you don't need to instantiate it.

 * **The `Assets` class has four main responsibilities:**
 * 1. Allows users to map URLs to keys and resolve them according to the user's browser capabilities
 * 2. Loads the resources and transforms them into assets that developers understand.
 * 3. Caches the assets and provides a way to access them.
 * 4. Allow developers to unload assets and clear the cache.
 *
 *
 * **It also has a few advanced features:**
 * 1. Allows developers to provide a {@link assets.Manifest} upfront of all assets and help manage
 * them via {@link assets.AssetsBundles Bundles}.
 * 2. Allows users to background load assets. Shortening (or eliminating) load times and improving UX. With this feature,
 * in-game loading bars can be a thing of the past!
 * @example
 * import { Assets } from 'pixi.js';
 *
 * const bunny = await Assets.load('bunny.png');

 * 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

/**
 * Utility class for maintaining reference to a collection
 * of Textures on a single Spritesheet.
 *
 * 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":16,"y":16}
 *         },
 *         "enemy2.png":
 *         {
 *             "frame": {"x":103,"y":35,"w":32,"h":32},
 *             "spriteSourceSize": {"x":0,"y":0,"w":32,"h":32},
 *             "sourceSize": {"w":32,"h":32},
 *             "anchor": {"x":16,"y":16}
 *         },
 *         "button.png":
 *         {
 *             "frame": {"x":1,"y":1,"w":100,"h":100},
 *             "spriteSourceSize": {"x":0,"y":0,"w":100,"h":100},
 *             "sourceSize": {"w":100,"h":100},
 *             "anchor": {"x":0,"y":0},
 *             "borders": {"left":35,"top":35,"right":35,"bottom":35}
 *         }
 *     },
 *
 *     "animations": {
 *         "enemy": ["enemy1.png","enemy2.png"]
 *     },
 *
 *     "meta": {
 *         "image": "sheet.png",
 *         "format": "RGBA8888",
 *         "size": {"w":136,"h":102},
 *         "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',
 *     src: 'images/spritesheet.json',
 *     data: {texture: sheetTexture} // using of preloaded texture
 * });
 * const sheet = await Assets.load('atlas')
 * ```
 *
 * or:
 *
 * ```js
 * import { Assets } from 'pixi.js';
 *
 * Assets.add({
 *     alias: 'atlas',
 *     src: 'images/spritesheet.json',
 *     data: {imageFilename: 'my-spritesheet.2x.avif'} // using of custom filename located in "images/my-spritesheet.2x.avif"
 * });
 * const sheet = await Assets.load('atlas')
