Description: 高级顶层窗口是一种无标题栏、菜单、工具条的一种常居顶层的窗口，最常见的例子就是输入法窗口，比如智能ABC窗口。这类窗口的特点除了上边所说的，最重要的就是窗口移动。普通窗口移动是通过标题栏由系统自动实现的，对于这类窗口就无法依靠系统了，需要手工实现。实现的方法有两种：
手工处理WM_MOVE、WM_LBUTTONUP消息，并根据鼠标的移动自己实现窗口移动过程中的绘制；
在WM_MOVE消息处理函数中通过向自己发送参数wParam为HTCAPTION lParam为鼠标位置的WM_NCLBUTTONDOWN消息实现窗口移动，此时窗口移动过程的绘制由系统实现。
显然，后者较前者简单。本文采用后者。-top window is a non-title bar, menus, tools of a regular Habitat top of the window, the most common example is the input window, such as smart window ABC.
