Register mouse devices on cocoa
It would have been nice to ensure that a device is registered already in mouseEnteredImpl(); but in that context, NSEvent.deviceID is always 0, and we can't find out anything else about the device. QWindowSystemInterface::handleEnterEvent() doesn't currently take a QPointingDevice either. In handleMouseEvent() and scrollWheel(), deviceID seems unique for each trackpad or Magic Mouse, but 0 for any plain USB mouse. There, the first mouse that the user interacts with becomes primaryPointingDevice(): its deviceID is assigned to systemID (except if deviceID == 0, we use 1 instead, to avoid the auto-incrementing device ID assignment in the QInputDevicePrivate ctor.) When scrolling occurs, we update the capabilities to have PixelScroll if theEvent.hasPreciseScrollingDeltas. So over time, QInputDevice::devices() should build up to a complete list, with capabilities() also distinguishing plain mice from those that have the PixelScroll capability. And in the common case that the user has only one Apple pointing device, it becomes primaryPointingDevice().
