/*******************************************************************************
* @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
