 * 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
 * import { Sprite, Texture } from 'pixi.js';
 *
 * const texture = Texture.from('assets/image.png');
 * const sprite1 = new Sprite(texture);
 * const sprite2 = new 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
 * import { Sprite, Texture } from 'pixi.js';
 *
 * const texture = Texture.from('assets/image.svg');
 * const sprite1 = new 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 [#3085]{@link https://github.com/pixijs/pixijs/issues/3085}.
