The important part is that the driver must know when there is added or removed a finger as touchpads sends the avarage positions of the fingers. Adding or removing a finger moves the mouse if the driver does nothing. There are other questions, if the API is to be used by a general user touchpad driver. Is there a way to communicate the resolution of the x,y and z coordinates to the user driver? (not only min/max). How do I tell that the y coordinate is reversed (gliderpointer) ?
