<pre>When an absolute pointer motion event is handled in the drm backend, it's
requested absolute x,y values are passed to notify_motion() and treated as a
relative x,y values.
For example, I have a test program that creates an absolute uinput pointer
device. Weston detects the device correctly as:
[18:34:57.184] input device MY UINPUT ABS POINTER, /dev/input/event10 is a
pointer caps = absolute-motion button
However, when my test program moves the absolute pointer to, say, x=200 y=100,
Weston actually moves it to x=200+"current x" y=100+"current y". This is a
regression since it was recently working fine...
