/**
 * System that manages the generation of textures from display objects in the renderer.

 * @example
 * ```ts
 * import { Application, Sprite, Graphics } from 'pixi.js';
 *
 * const app = new Application();
 * await app.init();
 *
 * // Create a complex display object
 * const container = new Container();
 *
 * const graphics = new Graphics()

 *     .fill('red');
 *
 * const sprite = new Sprite(texture);

 * // Generate a texture from the container
 * const generatedTexture = app.renderer.textureGenerator.generateTexture({

 *
 * // Use the generated texture
 * const newSprite = new Sprite(generatedTexture);
 * app.stage.addChild(newSprite);
 *
 * // Clean up when done
 * generatedTexture.destroy(true);
 * ```
 *
 * Features:
 * - Convert any display object to a texture
 * - Support for custom regions and resolutions
 * - Anti-aliasing support
 * - Background color configuration
 * - Texture source options customization
 *
 * Common Use Cases:
 * - Creating texture atlases dynamically
 * - Caching complex container content
 * - Generating thumbnails
 * - Creating reusable textures from rendered content
 *
 * Performance Considerations:
 * - Generating textures is relatively expensive
 * - Cache results when possible
 * - Be mindful of resolution and size
 * - Clean up unused textures

 * @see {@link AbstractRenderer.generateTexture} For the main renderer method
