 * In PixiJS v6 this has changed from true to false by default, to allow WebGL to work in as many scenarios as possible.
 * However, some users may have a poor experience, for example, if a user has a gpu or driver version blacklisted by the
 * browser.
 *
 * If your application requires high performance rendering, you may wish to set this to false.

 *
 * 1: Use the `pixi.js-legacy` package, which includes a Canvas renderer as a fallback in case high performance WebGL is
 *    not supported.
 *
 * 2: Call `isWebGLSupported` (which if found in the PIXI.utils package) in your code before attempting to create a PixiJS
 *    renderer, and show an error message to the user if the function returns false, explaining that their device & browser
 *    combination does not support high performance WebGL.
 *    This is a much better strategy than trying to create a PixiJS renderer and finding it then fails.

 * ## Transforms
 *
 * The [transform]{@link DisplayObject#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 PIXI.DisplayObject#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 PIXI.DisplayObject#position}</td>
 *       <td>
 *         Translation. This is the position of the [pivot]{@link PIXI.DisplayObject#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 PIXI.DisplayObject#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 PIXI.DisplayObject#pivot}.
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[rotation]{@link PIXI.DisplayObject#rotation}</td>
 *       <td>
 *          Rotation. This will rotate the display object's projection by this angle (in radians).
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>[skew]{@link PIXI.DisplayObject#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 communtative operations. Indeed,
 *         because rotation is essentially a careful combination of the two.
 *         </p>
 *       </td>
 *     </tr>
 *     <tr>
 *       <td>angle</td>
 *       <td>Rotation. This is an alias for [rotation]{@link PIXI.DisplayObject#rotation}, but in degrees.</td>
 *     </tr>

 *       <td>x</td>

 *         Implemented in [Container]{@link PIXI.Container}. Scaling. The width property calculates scale.x by dividing
 *         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.
 *       </td>

 *     <tr>
 *       <td>height</td>
 *       <td>
 *         Implemented in [Container]{@link PIXI.Container}. Scaling. The height property calculates scale.y by dividing

 *         is no concept of user-defined height.
 *       </td>
 *     </tr>
 *   </tbody>
 * </table>
 *
 * ## Bounds
 *
 * The bounds of a display object is defined by the minimum axis-aligned rectangle in world space that can fit
 * around it. The abstract `calculateBounds` method is responsible for providing it (and it should use the
 * `worldTransform` to calculate in world space).
 *
 * There are a few additional types of bounding boxes:
 *
 * | Bounds                | Description                                                                              |
 * | --------------------- | ---------------------------------------------------------------------------------------- |
 * | World Bounds          | This is synonymous is the regular bounds described above. See `getBounds()`.             |
 * | Local Bounds          | This the axis-aligned bounding box in the parent's local space. See `getLocalBounds()`.  |
 * | Render Bounds         | The bounds, but including extra rendering effects like filter padding.                   |
 * | Projected Bounds      | The bounds of the projected display object onto the screen. Usually equals world bounds. |
 * | Relative Bounds       | The bounds of a display object when projected onto a ancestor's (or parent's) space.     |
 * | Natural Bounds        | The bounds of an object in its own local space (not parent's space, like in local bounds)|
 * | Content Bounds        | The natural bounds when excluding all children of a `Container`.                         |
 *
 * ### calculateBounds
 *
 * [Container]{@link Container} already implements `calculateBounds` in a manner that includes children.
 *
 * But for a non-Container display object, the `calculateBounds` method must be overridden in order for `getBounds` and
 * `getLocalBounds` to work. This method must write the bounds into `this._bounds`.
 *
 * Generally, the following technique works for most simple cases: take the list of points
 * forming the "hull" of the object (i.e. outline of the object's shape), and then add them
 * using {@link PIXI.Bounds#addPointMatrix}.
 *
 * ```js
 * calculateBounds(): void
 * {
 *     const points = [...];
 *
 *     for (let i = 0, j = points.length; i < j; i++)
 *     {
 *         this._bounds.addPointMatrix(this.worldTransform, points[i]);
 *     }
 * }
 * ```
 *
 * You can optimize this for a large number of points by using {@link PIXI.Bounds#addVerticesMatrix} to pass them
 * in one array together.
 *
 * ## Alpha
 *
 * 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).
 *
 * The alpha with which the display object will be rendered is called the [worldAlpha]{@link PIXI.DisplayObject#worldAlpha}.
 *
 * ## Renderable vs Visible
 *
 * 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.
 *
 * It is recommended that applications use the `renderable` property for culling. See
 * [@pixi-essentials/cull]{@link https://www.npmjs.com/package/@pixi-essentials/cull} or
 * [pixi-cull]{@link https://www.npmjs.com/package/pixi-cull} for more details.
 *
 * Otherwise, to prevent an object from rendering in the general-purpose sense - `visible` is the property to use. This
 * one is also better in terms of performance.

     * be recalculated. The upside, however, is that calling `getBounds` once on a container will indeed update
     * the bounds of all children (the whole subtree, in fact). This side effect should be exploited by using
     * `displayObject._bounds.getRectangle()` when traversing through all the bounds in a scene graph. Otherwise,
     * calling `getBounds` on each object in a subtree will cause the total cost to increase quadratically as
     * its height increases.
     *
     * The transforms of all objects in a container's **subtree** and of all **ancestors** are updated.
     * The world bounds of all display objects in a container's **subtree** will also be recalculated.
     *
     * The `_bounds` object stores the last calculation of the bounds. You can use to entirely skip bounds
     * calculation if needed.
     *
     * ```js
     * const lastCalculatedBounds = displayObject._bounds.getRectangle(optionalRect);
     * ```
     *
     * Do know that usage of `getLocalBounds` can corrupt the `_bounds` of children (the whole subtree, actually). This
     * is a known issue that has not been solved. See [getLocalBounds]{@link PIXI.DisplayObject#getLocalBounds} for more
     * details.
     *
     * `getBounds` should be called with `skipUpdate` equal to `true` in a render() call. This is because the transforms
     * are guaranteed to be update-to-date. In fact, recalculating inside a render() call may cause corruption in certain
     * cases.
     * @param skipUpdate - Setting to `true` will stop the transforms of the scene graph from
     *  being updated. This means the calculation returned MAY be out of date BUT will give you a
     *  nice performance boost.

         * object to the shape of the mask applied to it. In PixiJS a regular mask must be a
         * {@link PIXI.Graphics} or a {@link PIXI.Sprite} object. This allows for much faster masking in canvas as it
         * utilities shape clipping. Furthermore, a mask of an object must be in the subtree of its parent.
         * Otherwise, `getLocalBounds` may calculate incorrect bounds, which makes the container's width and height wrong.
         * To remove a mask, set this property to `null`.
         *
         * For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.
         * @example
         * const graphics = new PIXI.Graphics();
         * graphics.beginFill(0xFF3300);
         * graphics.drawRect(50, 250, 100, 100);
         * graphics.endFill();
         *
         * const sprite = new PIXI.Sprite(texture);
         * sprite.mask = graphics;
         * @todo At the moment, PIXI.CanvasRenderer doesn't support PIXI.Sprite as mask.

 *
 * A BaseRenderTexture takes a snapshot of any Display Object given to its render method. The position
 * and rotation of the given Display Objects is ignored. For example:
 *
 * ```js
 * let renderer = PIXI.autoDetectRenderer();
 * let baseRenderTexture = new PIXI.BaseRenderTexture({ width: 800, height: 600 });
 * let renderTexture = new PIXI.RenderTexture(baseRenderTexture);
 * let sprite = PIXI.Sprite.from("spinObj_01.png");

 * sprite.position.y = 600/2;
 * sprite.anchor.x = 0.5;
 * sprite.anchor.y = 0.5;
 *
 * renderer.render(sprite, {renderTexture});
 * ```
 *
 * The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0
 * you can clear the transform
 *
 * ```js
 *
 * sprite.setTransform()
 *
 * let baseRenderTexture = new PIXI.BaseRenderTexture({ width: 100, height: 100 });

 * A texture stores the information that represents an image or part of an image.
 *
 * It cannot be added to the display list directly; instead use it as the texture for a Sprite.
 * If no frame is provided for a texture, then the whole image is used.
 *
 * You can directly create a texture from an image and then reuse it multiple times like this :
 *
 * ```js
 * let texture = PIXI.Texture.from('assets/image.png');
 * let sprite1 = new PIXI.Sprite(texture);
 * let sprite2 = new PIXI.Sprite(texture);
 * ```
 *
 * If you didnt pass the texture frame to constructor, it enables `noFrame` mode:
 * it subscribes on baseTexture events, it automatically resizes at the same time as baseTexture.
 *
 * Textures made from SVGs, loaded or not, cannot be used before the file finishes processing.
 * You can check for this by checking the sprite's _textureID property.
 * ```js
 * var texture = PIXI.Texture.from('assets/image.svg');
 * var sprite1 = new PIXI.Sprite(texture);
 * //sprite1._textureID should not be undefined if the texture has finished processing the SVG file
 * ```
 * You can use a ticker or rAF to ensure your sprites load the finished textures after processing. See issue #3068.

/**
 * A RenderTexture is a special texture that allows any PixiJS display object to be rendered to it.
 *
 * __Hint__: All DisplayObjects (i.e. Sprites) that render to a RenderTexture should be preloaded
 * otherwise black rectangles will be drawn instead.
 *
 * __Hint-2__: The actual memory allocation will happen on first render.
 * You shouldn't create renderTextures each frame just to delete them after, try to reuse them.
 *
 * A RenderTexture takes a snapshot of any Display Object given to its render method. For example:
 *
 * ```js
 * let renderer = PIXI.autoDetectRenderer();
 * let renderTexture = PIXI.RenderTexture.create({ width: 800, height: 600 });
 * let sprite = PIXI.Sprite.from("spinObj_01.png");
 *
 * sprite.position.x = 800/2;
 * sprite.position.y = 600/2;
 * sprite.anchor.x = 0.5;
 * sprite.anchor.y = 0.5;
 *
 * renderer.render(sprite, {renderTexture});
 * ```
 * Note that you should not create a new renderer, but reuse the same one as the rest of the application.
 *
 * The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0
 * you can clear the transform
 *
 * ```js
 *
 * sprite.setTransform()
 *
 * let renderTexture = new PIXI.RenderTexture.create({ width: 100, height: 100 });
 *
 * renderer.render(sprite, {renderTexture});  // Renders to center of RenderTexture

 * - Samplers cannot be used in ubo's (a GPU limitation)
 * - You must ensure that the object you pass in exactly matches in the shader ubo structure.
 * Otherwise, weirdness will ensue!
 * - The name of the ubo object added to the group must match exactly the name of the ubo in the shader.
 *
 * ```

/**
 * System plugin to the renderer to manage filters.
 *
 * ## Pipeline
 *
 * The FilterSystem executes the filtering pipeline by rendering the display-object into a texture, applying its
 * [filters]{@link PIXI.Filter} in series, and the last filter outputs into the final render-target.
 *
 * The filter-frame is the rectangle in world space being filtered, and those contents are mapped into
 * `(0, 0, filterFrame.width, filterFrame.height)` into the filter render-texture. The filter-frame is also called
 * the source-frame, as it is used to bind the filter render-textures. The last filter outputs to the `filterFrame`
 * in the final render-target.
 *
 * ## Usage
 *
 * {@link PIXI.Container#renderAdvanced} is an example of how to use the filter system. It is a 3 step process:
 *
 * **push**: Use {@link PIXI.FilterSystem#push} to push the set of filters to be applied on a filter-target.
 * **render**: Render the contents to be filtered using the renderer. The filter-system will only capture the contents
 *      inside the bounds of the filter-target. NOTE: Using {@link PIXI.Renderer#render} is
 *      illegal during an existing render cycle, and it may reset the filter system.
 * **pop**: Use {@link PIXI.FilterSystem#pop} to pop & execute the filters you initially pushed. It will apply them
 *      serially and output to the bounds of the filter-target.

/**
 * A filter is a special shader that applies post-processing effects to an input texture and writes into an output
 * render-target.
 *
 * {@link http://pixijs.io/examples/#/filters/blur-filter.js Example} of the
 * {@link PIXI.filters.BlurFilter BlurFilter}.
 *
 * ### Usage
 * Filters can be applied to any DisplayObject or Container.
 * PixiJS' `FilterSystem` renders the container into temporary Framebuffer,
 * then filter renders it to the screen.
 * Multiple filters can be added to the `filters` array property and stacked on each other.
 *
 * ```
 * const filter = new PIXI.Filter(myShaderVert, myShaderFrag, { myUniform: 0.5 });
 * const container = new PIXI.Container();
 * container.filters = [filter];
 * ```
 *
 * ### Previous Version Differences
 *
 * In PixiJS **v3**, a filter was always applied to _whole screen_.
 *
 * In PixiJS **v4**, a filter can be applied _only part of the screen_.
 * Developers had to create a set of uniforms to deal with coordinates.
 *
 * In PixiJS **v5** combines _both approaches_.
 * Developers can use normal coordinates of v3 and then allow filter to use partial Framebuffers,
 * bringing those extra uniforms into account.
 *
 * Also be aware that we have changed default vertex shader, please consult
 * {@link https://github.com/pixijs/pixi.js/wiki/v5-Creating-filters Wiki}.
 *
 * ### Frames
 *
 * The following table summarizes the coordinate spaces used in the filtering pipeline:
 *
 * <table>
 * <thead>
 *   <tr>
 *     <th>Coordinate Space</th>
 *     <th>Description</th>
 *   </tr>
 * </thead>
 * <tbody>
 *   <tr>
 *     <td>Texture Coordinates</td>
 *     <td>
 *         The texture (or UV) coordinates in the input base-texture's space. These are normalized into the (0,1) range along
 *         both axes.
 *     </td>
 *   </tr>
 *   <tr>
 *     <td>World Space</td>
 *     <td>
 *         A point in the same space as the world bounds of any display-object (i.e. in the scene graph's space).
 *     </td>
 *   </tr>
 *   <tr>
 *     <td>Physical Pixels</td>
 *     <td>
 *         This is base-texture's space with the origin on the top-left. You can calculate these by multiplying the texture
 *         coordinates by the dimensions of the texture.
 *     </td>
 *   </tr>
 * </tbody>
 * </table>
 *
 * ### Built-in Uniforms
 *
 * PixiJS viewport uses screen (CSS) coordinates, `(0, 0, renderer.screen.width, renderer.screen.height)`,
 * and `projectionMatrix` uniform maps it to the gl viewport.
 *
 * **uSampler**
 *
 * The most important uniform is the input texture that container was rendered into.
 * _Important note: as with all Framebuffers in PixiJS, both input and output are
 * premultiplied by alpha._
 *
 * By default, input normalized coordinates are passed to fragment shader with `vTextureCoord`.
 * Use it to sample the input.
 *
 * ```
 * const fragment = `
 * varying vec2 vTextureCoord;
 * uniform sampler2D uSampler;
 * void main(void)
 * {
 *    gl_FragColor = texture2D(uSampler, vTextureCoord);
 * }
 * `;
 *
 * const myFilter = new PIXI.Filter(null, fragment);
 * ```
 *
 * This filter is just one uniform less than {@link PIXI.filters.AlphaFilter AlphaFilter}.
 *
 * **outputFrame**
 *
 * The `outputFrame` holds the rectangle where filter is applied in screen (CSS) coordinates.
 * It's the same as `renderer.screen` for a fullscreen filter.
 * Only a part of  `outputFrame.zw` size of temporary Framebuffer is used,
 * `(0, 0, outputFrame.width, outputFrame.height)`,
 *
 * Filters uses this quad to normalized (0-1) space, its passed into `aVertexPosition` attribute.
 * To calculate vertex position in screen space using normalized (0-1) space:
 *
 * ```
 * vec4 filterVertexPosition( void )
 * {
 *     vec2 position = aVertexPosition * max(outputFrame.zw, vec2(0.)) + outputFrame.xy;
 *     return vec4((projectionMatrix * vec3(position, 1.0)).xy, 0.0, 1.0);
 * }
 * ```
 *
 * **inputSize**
 *
 * Temporary framebuffer is different, it can be either the size of screen, either power-of-two.
 * The `inputSize.xy` are size of temporary framebuffer that holds input.
 * The `inputSize.zw` is inverted, it's a shortcut to evade division inside the shader.
 *
 * Set `inputSize.xy = outputFrame.zw` for a fullscreen filter.
 *
 * To calculate input normalized coordinate, you have to map it to filter normalized space.
 * Multiply by `outputFrame.zw` to get input coordinate.
 * Divide by `inputSize.xy` to get input normalized coordinate.
 *
 * ```
 * vec2 filterTextureCoord( void )
 * {
 *     return aVertexPosition * (outputFrame.zw * inputSize.zw); // same as /inputSize.xy
 * }
 * ```
 * **resolution**
 *
 * The `resolution` is the ratio of screen (CSS) pixels to real pixels.
 *
 * **inputPixel**
 *
 * `inputPixel.xy` is the size of framebuffer in real pixels, same as `inputSize.xy * resolution`
 * `inputPixel.zw` is inverted `inputPixel.xy`.
 *
 * It's handy for filters that use neighbour pixels, like {@link PIXI.filters.FXAAFilter FXAAFilter}.
 *
 * **inputClamp**
 *
 * If you try to get info from outside of used part of Framebuffer - you'll get undefined behaviour.
 * For displacements, coordinates has to be clamped.
 *
 * The `inputClamp.xy` is left-top pixel center, you may ignore it, because we use left-top part of Framebuffer
 * `inputClamp.zw` is bottom-right pixel center.
 *
 * ```
 * vec4 color = texture2D(uSampler, clamp(modifiedTextureCoord, inputClamp.xy, inputClamp.zw))
 * ```
 * OR
 * ```
 * vec4 color = texture2D(uSampler, min(modifigedTextureCoord, inputClamp.zw))
 * ```
 *
 * ### Additional Information
 *
 * Complete documentation on Filter usage is located in the
 * {@link https://github.com/pixijs/pixi.js/wiki/v5-Creating-filters Wiki}.
 *
 * Since PixiJS only had a handful of built-in filters, additional filters can be downloaded
 * {@link https://github.com/pixijs/pixi-filters here} from the PixiJS Filters repository.

/**
 * System plugin to the renderer to manage masks.
 *
 * There are three built-in types of masking:
 * **Scissor Masking**: Scissor masking discards pixels that are outside of a rectangle called the scissor box. It is
 *  the most performant as the scissor test is inexpensive. However, it can only be used when the mask is rectangular.
 * **Stencil Masking**: Stencil masking discards pixels that don't overlap with the pixels rendered into the stencil
 *  buffer. It is the next fastest option as it does not require rendering into a separate framebuffer. However, it does
 *  cause the mask to be rendered **twice** for each masking operation; hence, minimize the rendering cost of your masks.
 * **Sprite Mask Filtering**: Sprite mask filtering discards pixels based on the red channel of the sprite-mask's
 *  texture. (Generally, the masking texture is grayscale). Using advanced techniques, you might be able to embed this
 *  type of masking in a custom shader - and hence, bypassing the masking system fully for performance wins.
 *
 * The best type of masking is auto-detected when you `push` one. To use scissor masking, you must pass in a `Graphics`
 * object with just a rectangle drawn.
 *
 * ## Mask Stacks
 *
 * In the scene graph, masks can be applied recursively, i.e. a mask can be applied during a masking operation. The mask
 * stack stores the currently applied masks in order. Each {@link PIXI.BaseRenderTexture} holds its own mask stack, i.e.
 * when you switch render-textures, the old masks only applied when you switch back to rendering to the old render-target.

 * | {@link PIXI.BatchSystem}             | This manages object renderers that defer rendering until a flush.             |
 * | {@link PIXI.ContextSystem}           | This manages the WebGL context and extensions.                                |
 * | {@link PIXI.EventSystem}             | This manages UI events.                                                       |
 * | {@link PIXI.FilterSystem}            | This manages the filtering pipeline for post-processing effects.              |

 * | {@link PIXI.GeometrySystem}          | This manages geometries & buffers, which are used to draw object meshes.      |

 * @param {boolean} [options.autoDensity=false] -
 *  Whether the CSS dimensions of the renderer's view should be resized automatically.
 * @param {number} [options.backgroundAlpha=1] -
 *  Transparency of the background color, value from `0` (fully transparent) to `1` (fully opaque).
 * @param {number} [options.backgroundColor=0x000000] -
 *  The background color used to clear the canvas. It accepts hex numbers (e.g. `0xff0000`).

 * @param {PIXI.IRenderingContext} [options.context] - **WebGL Only.** User-provided WebGL rendering context object.
 * @param {boolean} [options.forceCanvas=false] -
 *  Force using {@link PIXI.CanvasRenderer}, even if WebGL is available. This option only is available when

 *  The resolution / device pixel ratio of the renderer.
 * @param {boolean} [options.transparent] -
 *  **Deprecated since 6.0.0, Use `backgroundAlpha` instead.** \
 *  `true` sets `backgroundAlpha` to `0`, `false` sets `backgroundAlpha` to `1`.
 * @param {boolean|'notMultiplied'} [options.useContextAlpha=true] -
 *  Pass-through value for canvas' context attribute `alpha`. This option is for cases where the
 *  canvas needs to be opaque, possibly for performance reasons on some older devices.
 *  If you want to set transparency, please use `backgroundAlpha`. \
 *  **WebGL Only:** When set to `'notMultiplied'`, the canvas' context attribute `alpha` will be
 *  set to `true` and `premultipliedAlpha` will be to `false`.

/**
 * Resource for compressed texture formats, as follows: S3TC/DXTn (& their sRGB formats), ATC, ASTC, ETC 1/2, PVRTC.
 *
 * Compressed textures improve performance when rendering is texture-bound. The texture data stays compressed in
 * graphics memory, increasing memory locality and speeding up texture fetches. These formats can also be used to store
 * more detail in the same amount of memory.
 *
 * For most developers, container file formats are a better abstraction instead of directly handling raw texture
 * data. PixiJS provides native support for the following texture file formats (via {@link PIXI.Loader}):
 *
 * **.dds** - the DirectDraw Surface file format stores DXTn (DXT-1,3,5) data. See {@link PIXI.DDSLoader}
 * **.ktx** - the Khronos Texture Container file format supports storing all the supported WebGL compression formats.
 *  See {@link PIXI.KTXLoader}.
 * **.basis** - the BASIS supercompressed file format stores texture data in an internal format that is transcoded
 *  to the compression format supported on the device at _runtime_. It also supports transcoding into a uncompressed
 *  format as a fallback; you must install the `@pixi/basis-loader`, `@pixi/basis-transcoder` packages separately to
 *  use these files. See {@link PIXI.BasisLoader}.
 *
 * The loaders for the aforementioned formats use `CompressedTextureResource` internally. It is strongly suggested that
 * they be used instead.
 *
 * ## Working directly with CompressedTextureResource
 *
 * Since `CompressedTextureResource` inherits `BlobResource`, you can provide it a URL pointing to a file containing
 * the raw texture data (with no file headers!):
 *
 * ```js
 * // The resource backing the texture data for your textures.
 * // NOTE: You can also provide a ArrayBufferView instead of a URL. This is used when loading data from a container file
 * //   format such as KTX, DDS, or BASIS.
 * const compressedResource = new PIXI.CompressedTextureResource("bunny.dxt5", {
 *   format: PIXI.INTERNAL_FORMATS.COMPRESSED_RGBA_S3TC_DXT5_EXT,
 *   width: 256,
 *   height: 256
 * });
 *
 * // You can create a base-texture to the cache, so that future `Texture`s can be created using the `Texture.from` API.
 * const baseTexture = new PIXI.BaseTexture(compressedResource, { pmaMode: PIXI.ALPHA_MODES.NPM });
 *
 * // Create a Texture to add to the TextureCache
 * const texture = new PIXI.Texture(baseTexture);
 *
 * // Add baseTexture & texture to the global texture cache
 * PIXI.BaseTexture.addToCache(baseTexture, "bunny.dxt5");
 * PIXI.Texture.addToCache(texture, "bunny.dxt5");
 * ```

 * and some advanced functionality like tint (as of v4.5.6).
 *
 * Other more advanced functionality like masking, children, filters, etc will not work on sprites in this batch.

 * {
 *     let sprite = PIXI.Sprite.from("myImage.png");

/**
 * A BitmapText object will create a line or multiple lines of text using bitmap font.
 *
 * The primary advantage of this class over Text is that all of your textures are pre-generated and loading,
 * meaning that rendering is fast, and changing text has no performance implications.
 *
 * Supporting character sets other than latin, such as CJK languages, may be impractical due to the number of characters.
 *
 * To split a line you can use '\n', '\r' or '\r\n' in your string.
 *
 * PixiJS can auto-generate fonts on-the-fly using BitmapFont or use fnt files provided by:
 * http://www.angelcode.com/products/bmfont/ for Windows or
 * http://www.bmglyph.com/ for Mac.
 *
 * You can also use SDF, MSDF and MTSDF BitmapFonts for vector-like scaling appearance provided by:
 * https://github.com/soimy/msdf-bmfont-xml for SDF and MSDF fnt files or
 * https://github.com/Chlumsky/msdf-atlas-gen for SDF, MSDF and MTSDF json files
 *
 * A BitmapText can only be created when the font is loaded.
 *

/**
 * This namespace contains WebGL-only display filters that can be applied
 * to DisplayObjects using the {@link PIXI.DisplayObject#filters filters} property.
 *
 * Since PixiJS only had a handful of built-in filters, additional filters
 * can be downloaded {@link https://github.com/pixijs/pixi-filters here} from the
 * PixiJS Filters repository.
 *
 * All filters must extend {@link PIXI.Filter}.
 * @example
 * // Create a new application
 * const app = new PIXI.Application();
 *
 * // Draw a green rectangle
 * const rect = new PIXI.Graphics()
 *     .beginFill(0x00ff00)
 *     .drawRect(40, 40, 200, 200);
 *
 * // Add a blur filter
 * rect.filters = [new PIXI.filters.BlurFilter()];
 *
 * // Display rectangle
 * app.stage.addChild(rect);
 * document.body.appendChild(app.view);
 * @namespace PIXI.filters
