Subject: [PATCH] Send time of point within stroke.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, only the time of the first point in the stroke was given to handle_point. Send a more specific time for each point within the stroke based on the point’s index within the stroke. For Livescribe pens, the time between each sample is 1000/75ms = 13.3ms.
