Bug Description
Touchpads on laptops should be able to work with the uTouch stack, even if they aren't truly MT. Let's see what we can do about adding as much support as possible.

Turns out this can be supported quite easily by a patch to grail. The level of support could in principle vary, but this is the current target:
Single finger motion: Can be supported on all devices that report BTN_TOUCH or BTN_TOOL_FINGER, which amounts to just about every device on the market.
Multi-finger tap and drag: A maximum of four fingers supported if the device reports any of BTN_TOOL_DOUBLETAP, BTN_TOOL_TRIPLETAP, BTN_TOOL_QUADTAP.
Pinch and Rotate: Not available using legacy events.
