Tang Haixiang efc02f9cc3 xcb: Delete touch points without target windows ... When XCB_INPUT_TOUCH_BEGIN closes a popup, we then receive XCB_INPUT_TOUCH_END, and cannot find a target window (because it's destroyed). If we don't deliver it, we need to at least clear the stored point from QPointingDevicePrivate::activePoints. Then when we deliver the next touch press, m_fakeMouseSourcePointId also needs to be reset. It's now even more paramount that autotests (and real-world touchscreens) must never omit any active touchpoint from a touch event. If a point doesn't move, it must be included in the QTouchEvent, with Stationary state. If not, QGuiApp::processTouchEvent() could generate multiple TouchBegin events in a row, which gets other bits of logic confused, here and there.
