<div>
<pre>Devices with uneven horizontal/vertical resolution are accelerated unevenly.
e.g. on the x220t, the touchpad is almost twice as wide as high. The resolution
reflects this:
Event code 0 (ABS_X)
Value 2618
Min 1472
Max 5472
Resolution 75
Event code 1 (ABS_Y)
Value 2482
Min 1408
Max 4448
Resolution 129
the acceleration code needs to take this resolution into account to pre-adjust
the coordinates. The goal is that a circle on the device reflects a circle on
the screen.</pre>
