/**
 * 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:
 * @example
 * import { autoDetectRenderer, RenderTexture, Sprite } from 'pixi.js';
 *
 * const renderer = autoDetectRenderer();
 * const renderTexture = RenderTexture.create({ width: 800, height: 600 });
 * const sprite = 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
 *
 * sprite.setTransform();
 *
 * const renderTexture = new RenderTexture.create({ width: 100, height: 100 });
 *
 * renderer.render(sprite, { renderTexture });  // Renders to center of RenderTexture
 * @memberof PIXI
