On button down update cumulative to current x and y, instead of previous



When a button click and new coordinates get reported in one go we sync the
cumulative coordinates to the old x and y, rather then the newly reported ones.

This keeping of the old coordinates causes the following issue:
-touch the touchpad in its right click area
-let go of the touchpad
-rapidly click in the left click area (or middle area), so that the
 new location and the click get reported in one syn (may require some
 practicing with evemu-record to reproduce)
-the driver registers the click as a right click because it uses the
 old coordinates from the cumulative coordinates to determine the
 click location
