Instead of an explicit tablet mode that device must be changed into, let the caller decide which coordinates are preferred. The tablet mode may be application-specific and usually depends on the tool as well. This patch adds an interface to get a motion delta for the x/y axes in pixel-like coordinates. libinput provides some magic to convert the tablet data into something that resembles pixels from a mouse motion. For unaccelerated relative motion, the caller should use the mm values from the tablet and calculate deltas manually.
