Debian bug #190802
From: Chung-chieh Shan <ke**@di**.edu>

Many laptop pointer devices "drift" over time.  This causes workrave to
detect activity when there is in fact none.  The following patch makes
workrave's pointer activity detection less sensitive and take drift into
account, so as to address this problem.

Thank you.
