	// [触屏模型] 触摸只做两件事，不做任何“触摸→鼠标”的归一化：
	//   ①点击：由 TOUCHUP 在确认未拖动后派发 BUTTONDOWN/UP，
	//         由 CButtonUI 等控件原生 Activate()；
	//   ②滚动：WM_TOUCH 直接派发 UIEVENT_TOUCHDOWN/MOVE/UP（见 OnTouchInput），
	//         容器据此 1:1 跟手平移、滚动条据此拖滑块。
	//   “轻点 vs 拖拽”使用 m_bTouchMoved 区分，拖动不会激活控件。

	// WM_TOUCH 消息 ID 同样受 `#if _WIN32_WINNT >= 0x0601` 保护，DuiLib 工程未定义
	// _WIN32_WINNT（StdAfx.h 兜底为 XP）→ 必须自行声明，否则 switch 里引用该消息 ID
	// 会报 C2065（未声明的标识符）与 C2051（case 表达式不是常量）。实测固定值 0x0240。
	// 注：Win7+ 段受保护的不仅有结构体与函数，**消息 ID 与辅助宏同样在内**，
	//     TOUCH_COORD_TO_PIXEL 也在上面用 #ifndef 兜底，原因相同。

	// WM_POINTER* 消息 ID（Win8+）。参考 nim_duilib NativeWindow_Windows::OnPointerMsgs。
	//
	// 为什么必须自行定义：这些宏在 winuser.h 里受 `#if _WIN32_WINNT >= 0x0602` 保护，
	// 而本工程编译目标是 0x0601（Win7），编译期不可见。用字面量绕过（数值固定）。
	//
	// 为什么必须处理：Win10 在 Pointer 栈可用时会优先投递 WM_POINTER*，而**不是** legacy
	// 的 WM_TOUCH。我们此前完全不处理这条通道 —— 一旦系统走了 Pointer 路径，窗口就
	// 既没有 WM_TOUCH 状态机、又没有触发鼠标提升，表现就是"什么都点不动"。
	// nim_duilib 的注释还明确指出：WM_POINTERCAPTURECHANGED 若不设置 bHandled，
	// 系统会把它转换成 WM_BUTTON 类消息 —— 说明系统确实在这两条通道间做隐式转换。

		//   msg=0x0247 WM_POINTERUP      w=0x60000CC7   HIWORD=0x6000  bit0=0  ✗
		//
		// 也就是说 **HIWORD 根本不是 MSDN 描述的 POINTER_INFO 位域**（0x6016/0x6017/0x6000
		// 这三个值里只有 bit0 在 0x6016→0x6017 之间来回抖，看不出 primary 语义）。
		// 后果极其隐蔽：
		//   · DOWN 恰好读到 bit0=1 ⇒ 蒙对了，手势能建立；
		//   · UPDATE 读到 bit0=0 ⇒ 被当成"非主指针"**全部丢掉**，实测 486/486 条全丢
		//     ⇒ 手势建立成功、抬手也能派发点击（UP 早已豁免），
		//     但**整个过程没有任何位移信息** ⇒ 表现为"能点击，但怎么划都滑不动"。
		//   · UP 读到 bit0=0 ⇒ 当初就踩过，已单独豁免。
		//
		// 结论（照搬 nim_duilib 的做法）：**不要再依赖这个位域做过滤**。
		// nim_duilib 的 OnPointerMsgs 虽然也写了 IS_POINTER_PRIMARY_WPARAM，
		// 但它只处理单指场景、且按 pointerId 取坐标，对错位不敏感。
		// 本项目改为：DOWN/UPDATE/UP 一律不做 primary 过滤，
		// 统一用 m_dwActivePointerId 精确配对（是不是"发起本次手势的那根手指"）——
		// 这个判据来自 pointerId（LOWORD，即日志里的 0x0CC7=3271），是可靠的。

	// [通道无关的滑动状态机] Begin / Update / End
	//
	// 背景（这是本文件里最容易踩坑的一块，先把结论写在前面）：
	//   "滑动"这件事在本库里的实现只有一份 —— 派发 UIEVENT_TOUCHMOVE，由
	//     · CScrollBarUI 消费 → 拖滑块；
	//     · 否则冒泡到 CContainerUI → 1:1 跟手平移；
	//     · 谁都不认时 → 合成 UIEVENT_SCROLLWHEEL（Δy 累加满 120 一次）。
	//   过去这三个函数体是**内联写在 OnTouchInput（WM_TOUCH 通道）里的**。
	//
	//   问题：Win10 上同一次触摸会在两条互相独立的通道上都产生消息
	//   （WM_TOUCH 与 WM_POINTER*），而"谁驱动本次手势"是运行时决定的：
	//     · 主窗口常常是 WM_TOUCH 先到 → 老代码能滑；
	//     · 弹框 / 被指针抢走的手势 ⇒ 只有 WM_POINTER* →
	//       **整段滑动逻辑一条都没执行** ⇒ 「滑不动」；
	//       同时 UP 走指针 → 归一化成 WM_LBUTTONUP → 原生点击路径，
	//       而 tap/drag 判定所需的 m_bTouchMoved 从未被置真 ⇒「滑动反触发点击」。
	//
	//   修法：把滑动逻辑抽成不关心通道的这三个函数，两条通道都调用同一套。
	//   于是"谁驱动手势"不再影响"能不能滑"，只影响消息从哪儿来。
	//
	// 状态机的三个相位：
	//   Begin  : 命中控件 + 找可滚容器 + 记起点/上一包点 + 复位位移标志
	//   Update : Δ=(pt - 上一包点) 去重 → 置 m_bTouchMoved → 派发 TOUCHMOVE → 可能合成滚轮
	//   End    : 派发 TOUCHUP → 返回"是否算轻点"（未越过拖拽阈值）
	//
	// ⚠️ 三条不变量：
	//   1) Begin 必须把 m_bTouchSlideActive 置真；End 必须置假 + 清释放态。
	//   2) Update/End 在 !m_bTouchSlideActive 时必须安全空转（另一条通道可能没走 Begin）。

		//   · MessageHandler 的 WM_LBUTTONDOWN 在 m_pEventTouch != NULL 时直接 break；
		//   · OnPointerInput 的 DOWN 也不再调 MessageHandler(WM_LBUTTONDOWN)。
		// ⇒ 唯一能告诉控件"用户按下了"的通道就是这一发 TOUCHDOWN。
		//
		// 而控件侧的点击状态机是**按下/抬起配对**的，例如 CButtonUI::DoEvent：
		//   UIEVENT_TOUCHDOWN → m_uButtonState |= UISTATE_PUSHED | UISTATE_CAPTURED
		//   UIEVENT_TOUCHUP   → 清 PUSHED|CAPTURED

		// BUTTONUP 分支（或进了也因守卫失败而跳过）⇒ **Activate 根本不被调用**
		// ⇒ 表现为"主窗口触摸点击全灭"。
		//
		// 另外：本函数**只发 TOUCHDOWN，不发 BUTTONDOWN** —— 这是有意为之。
		// 因为整个手势可能演变成拖动（滚动列表），此时不能让控件提前进入"已按下"的业务态；
		// 真正的点击由 UP 阶段依据 tap 判定（EndTouchSlideGesture 的返回值）成对合成

		// 关键：手指抬起后禁止"悬浮态复活"。
		// Windows 会为触摸补发合成的 WM_MOUSEMOVE；且真实 WM_MOUSELEAVE 在 m_bMouseTracking

		//   1) 本函数被调用时 m_pEventTouch 已经不再需要 —— TOUCHUP 已派发、捕获已释放、
		//      悬浮态已清。它的语义是"本次触摸进行中命中的控件"，手势结束就该失效。
		//   2) 但 `WM_LBUTTONUP` 的原生分支开头是：
		//        if (m_pEventTouch != NULL || m_bSuppressPromotedTouchMouse) { ...; break; }
		//      这个 break **把 ReleaseCapture() 一起跳过了**。
		//   3) 于是只要 m_pEventTouch 残留非 NULL，系统随后提升出来的那条 WM_LBUTTONUP
		//      就会"只清抑制位、不释放捕获"地溜过去 ⇒ 窗口持有 capture 不放。
		//   4) 持有 capture 期间，鼠标/指针消息被强制路由到本窗口，**别处一律点不动**；
		//      且 m_bSuppressPromotedTouchMouse 被反复清成 0，WM_LBUTTONDOWN 的守卫

		//   这里是手势收尾的公共清理。**两条路径都必须清**，缺一条就留下上面那个死锁。

		// 清理顺序要求：必须在下面读 m_pEventClick 的 tap 判定**之前**完成 ——

		// 本项目的对应标记：
		//   · m_pEventTouch        ← 触摸链的占用标记（BeginTouchSlideGesture 里置）
		//   · m_bPointerGestureActive ← 指针链的占用标记（下面 DOWN 分支里置）
		//
		// ⚠️⚠️ 【UP 必须放行，绝不能在这里 return true】⚠️⚠️
		// 这是实测踩过的坑，后果极严重（主窗口触摸点击全灭）：
		//   WM_POINTERUP 是**唯一**能把 m_bPointerGestureActive 归零的消息。
		//   早期版本把 DOWN/UPDATE/UP 不加区分地一起吞掉，于是：
		//     1) 用户第一次点击：WM_TOUCH 先到 ⇒ 这里把 UP 吃掉
		//        ⇒ m_bPointerGestureActive 永久停在 true（上一次手势的残留值）；
		//     2) 之后每次触摸的 WM_POINTERDOWN 都被当成"重复按下"挡掉
		//        ⇒ 再也不产生 POINTER-MSG DOWN ⇒ 该窗口彻底聋掉。
		//   正确做法：让路只压住"驱动点击"的两个消息（DOWN/UPDATE），UP 一律放行 ——
		//   放行后**只做状态清理、不派发 WM_LBUTTONUP**（本次点击本来就不归指针管）。
		//
		// ⚠️ 与上一版的关键差异：这里用 `m_pEventTouch != NULL` 而非时间戳。
		//   m_pEventTouch 的语义是"WM_TOUCH 手势进行中命中的控件"，
		//   它在 BeginTouchSlideGesture 里置、在 EndTouchSlideGesture 里清，
		//   生命周期与"WM_TOUCH 是否真的接管了本次手势"严格一致 —— 这正是我们想要的。
		//   用时间戳的旧写法会因"指针通道自己也写它"而恒真，导致点击全灭（已踩过）。
		//
		// ⚠️⚠️ 【两条标记同时为真是**正常**路径，绝不能"清洗"它】⚠️⚠️
		//
		// 曾经在这里写过一段"状态交叉"纠偏：发现 m_pEventTouch != NULL 且
		// m_bPointerGestureActive 为真，就认定异常，把 m_pEventTouch 置回 NULL。
		// 那是个**严重的误判**，直接造成"整个应用什么都点不动"（真机日志可复现）：
		//
		//   指针通道的 DOWN 分支会调 BeginTouchSlideGesture，而该函数**本来就会**
		//   把 m_pEventTouch 置成命中控件 —— 也就是说"指针手势进行中 + m_pEventTouch 非空"
		//   是每一次指针手势的**标准状态**，不是异常。
		//   于是那段"纠偏"在第一条 UPDATE 上就把 m_pEventTouch 抹成 NULL：
		//     · UpdateTouchSlideGesture 里 `if (m_pEventTouch == NULL) return;`
		//       ⇒ 位移信息全丢，永远不产生 TOUCHMOVE ⇒ 滑不动；
		//     · EndTouchSlideGesture 里 `if (m_pEventTouch == NULL)` 走早退路
		//       ⇒ 返回 false = "不算轻点" ⇒ 点击被静默吞掉 ⇒ 什么都点不动。
		//
		// [NIM] 对照：NIM 的两条通道标记（m_pEventTouch / m_pEventPointer）是**并列**的，

		// [触屏兼容] 不再过滤 Windows 为触摸模拟的鼠标消息（MOUSEEVENTF_FROMTOUCH）。
		// 触摸的“点击”正来自这些模拟的 WM_LBUTTONDOWN/UP，由原生鼠标路径交给 CButtonUI 等控件
		// Activate() 触发——而 DuiLib 的点击状态机依赖 WM_LBUTTONDOWN 设置 m_pEventClick，故绝不能
		// 在鼠标分支吞掉这些模拟消息（之前那样做会导致触摸与鼠标点击全失效）。
		// 为避免“拖拽=滚动”又“误点按钮”，改用 m_bTouchMoved：若本次手势发生位移，在 WM_LBUTTONUP 抑制点击。

		// ------------------------------------------------------------------
		// [对标 nim_duilib] WM_POINTER*（Win8+ 指针栈）归一化成鼠标消息。
		//
		// ⚠️ 这里的核心是【手势级让路】，不是"通道二选一"。改回二选一会立刻坏掉真模态弹框：
		//   本台收银机上 WM_TOUCH 的贪婪归属权卡在主窗口（MSDN：收到第一条触摸消息后
		//   所有触摸消息都发给该窗口，直到另一个窗口获得焦点），弹框被程序 SetFocus
		//   而非触摸点出焦点 ⇒ 弹框永远收不到 WM_TOUCH，只能收到按命中投递的 WM_POINTER*。
		//   所以指针通道必须始终开着，弹框才有输入源。
		//
		// 那怎么避免"两条通道产生两套 WM_LBUTTONDOWN/UP 把点击状态机打乱"（曾经导致
		// 所有窗口点击全失效）？答案是：**同一时刻只让一条通道驱动**。
		//   · 指针先 DOWN ⇒ m_bPointerGestureActive=true，本次手势内 OnTouchInput 直接忽略 WM_TOUCH；
		//   · WM_TOUCH 先 DOWN ⇒ m_pEventTouch 置位，本次手势内这里拒绝指针；
		//   · 手势一结束（UP / 超时 / 捕获被夺）立刻解禁，下一个手势可以换通道。
		//   让路只加在 UP 的"驱动点击"上：同一手势里两条通道的**按下**才是一对重复；
		//   UP/MOVE 一侧不加让路，避免某一侧的 UP 被误丢导致状态永久悬空。
		//   ⚠️ 【血的教训】曾经让路连 WM_POINTERUP 一起吞 —— UP 是唯一能解除
		//   m_bPointerGestureActive 的消息，吞掉它会让指针手势状态永久为真，
		//   随后的 WM_POINTERDOWN 全被当成"重复按下"挡掉 ⇒ 整个窗口触摸点击全灭。
		//   现在 UP/UPDATE 一律送到 OnPointerInput，由那里自行决定"只清状态"还是"派发点击"。
		//
		// 另外，只处理 DOWN/UP/UPDATE 三个真正驱动点击的消息；
		// ENTER/LEAVE/ACTIVATE/HWHEEL/CAPTURECHANGED 交回系统（返回 false），绝不吞掉。
		//
		// 注意：本项目 _WIN32_WINNT=0x0601，WM_POINTER* 宏在编译期不可见，
		// 只能用字面量常量区间判断（见文件头 PointerMsg 命名空间）。
