Touchpad stylus mode

[Jim Gettys]

I think there are two logical operations, given the though I've had on
the topic:

1) if the client explicitly asks for a absolute pointing device as a
secondary input device in the XInput , we give them exactly what they
ask for, telling them they have a tablet of the the appropriate size,
etc.

2) if not, and the tablet device is being "ored" into the default
pointing device with the capacitive sensor, then the area on the screen
that is reported as coordinates from the tablet sensor might want to be
pushed around on the screen, as the relative pointing device (touchpad)
pushes to the edge of the tablet.

How far we are from things working this way, I'll let Zephaniah answer.
