xwarppointer python script

"""Make the X cursor wrap-around.

Adapted from http://appdb.winehq.org/objectManager.php?sClass=version&iId=12599
to work around lack of relative mouse movement http://wiki.winehq.org/Bug6971
for Thief: Dark Shadows (and possibly others)

This version is a little kinder to your CPU than the shell script with
the busy-loop that starts a new process for every pointer query.

Awesome example! I cleaned it up a little, passed pylint for it and object-oriented it a bit here:
