Subject: [PATCH] ntrig tool separation and pen usages
Date: Tue, 23 Jun 2009 14:09:26 -0400	[thread overview]
Message-ID: <1245780566-8541-1-git-send-email-rafi@seas.upenn.edu> (raw)

When both touch and pen are active send a tool announcement before
sending any status changes so that event users may differentiate
which tool is changing.

Restored three usage codes used by the pen.
