Interaction with a touch screen is far less precise that with a mouse. When one clicks on a link with a finger, the single point of interaction is often not on the link. QTouchPoint gives a rect representing the area of the finger on the screen. This rect must be used to find something the user can interact with. To implement this task, QtWebkit needs to sample points in the rect, and find an element that will accepts a click. The rect is not always available, here are the cases to handle: -QTouchPoint has a rect -QTouchEvent is sent, but without a rect -> guess a rect -No QTouchEvent is sent, QMouseEvent is sent instead on a platform without mouse (Maemo, some Symbian, Windows Mobile) -> guess a rect if the platform is mobile
