The peculiar way we handle coordinates results in relative coordinates on absolute devices being added to the last value, then that value is mapped to the screen (taking the device dimensions into account). From that mapped value we get the final coordinates, both screen and device coordinates. To avoid uneven scaling on relative coordinates, they are pre-scaled by screen ratio:resolution:device ratio factor before being mapped. This ensures that a circle drawn on the device is a circle on the screen. Previously, we used the ratio to scale x up. Synaptics already does its own scaling based on the resolution and that is done by scaling y down by the ratio. So we can remove the code from the driver and get approximately the same behaviour here. Minor ABI bump, so we can remove this from synaptics.
