/*******************************************************************************
|
||
* @类: Control
|
||
* @摘要: 所有控件的抽象基类，定义通用接口和基础功能
|
||
* @描述:
|
||
* 提供控件的基本属性和方法，包括位置、尺寸、重绘标记等。
|
||
* 实现绘图状态保存和恢复机制，确保控件绘制不影响全局状态。
|
||
*
|
||
* @特性:
|
||
* - 定义控件基本属性（坐标、尺寸、脏标记）
|
||
* - 提供绘图状态管理（saveStyle/restoreStyle）
|
||
* - 声明纯虚接口（draw、handleEvent等）
|
||
* - 支持移动语义，禁止拷贝语义
|
||
*
|
||
* @使用场景: 作为所有具体控件类的基类，不直接实例化
|
||
* @所属框架: 星垣(StellarX) GUI框架
|
||
* @作者: 我在人间做废物
