/**
 * @esengine/ui - ECS-based UI System
 *
 * 基于 ECS 架构的 UI 系统，支持 WebGL 渲染
 * ECS-based UI system with WebGL rendering support
 *
 * @example
 * ```typescript
 * import {
 *     UIBuilder,
 *     UILayoutSystem,
 *     UIInputSystem,
 *     UIAnimationSystem,
 *     // ECS Render Systems
 *     UIRectRenderSystem,
 *     UITextRenderSystem,
 *     UIButtonRenderSystem,
 *     UIProgressBarRenderSystem,
 *     UISliderRenderSystem,
 *     UIScrollViewRenderSystem,
 *     getUIRenderCollector
 * } from '@esengine/ui';
 *
 * // 创建 UI Scene
 * const uiScene = world.createScene('ui');
 *
 * // 添加 UI 系统（按 updateOrder 自动排序）
 * // Add UI systems (auto-sorted by updateOrder)
 * uiScene.addSystem(new UILayoutSystem());           // Layout first
 * uiScene.addSystem(new UIInputSystem());            // Input handling
 * uiScene.addSystem(new UIAnimationSystem());        // Animation
 *
 * // 添加渲染系统（每个组件类型一个系统）
 * // Add render systems (one per component type)
 * uiScene.addSystem(new UIRectRenderSystem());       // Basic rectangles (order: 100)
 * uiScene.addSystem(new UIProgressBarRenderSystem());// Progress bars (order: 110)
 * uiScene.addSystem(new UISliderRenderSystem());     // Sliders (order: 111)
 * uiScene.addSystem(new UIScrollViewRenderSystem()); // Scroll views (order: 112)
 * uiScene.addSystem(new UIButtonRenderSystem());     // Buttons (order: 113)
 * uiScene.addSystem(new UITextRenderSystem());       // Text (order: 120)
 *
 * // 在渲染前清除收集器
 * // Clear collector before render
 * getUIRenderCollector().clear();
 *
 * // 使用 UIBuilder 创建元素
 * const ui = new UIBuilder(uiScene);
 *
 * const button = ui.button({
 *     x: 100, y: 100,
 *     width: 120, height: 40,
 *     label: 'Click Me',
 *     onClick: () => console.log('Clicked!')
 * });
 *
 * const progressBar = ui.progressBar({
 *     x: 100, y: 160,
 *     width: 200, height: 20,
 *     value: 75,
 *     maxValue: 100
 * });
 * ```
