From: Jason Gerecke <killert...@gmail.com>
When a pen is first able to to be sensed by the tablet, we would like
to inform userspace that a tool is nearby so that it can attempt to
perform palm rejection. Unfortunately, we don't know any information
about the tool that is nearby, so the best we can do is send a prox
event for a generic BTN_TOOL_PEN. If the pen later comes closer and
enters proximity, we can determine the actual tool type and send
BTN_TOOL_PEN out of prox if necessary.
