I looked it over and thought it was a pretty good spec so far. The one
area of concern I had was about the touch shape. The spec only provides
for radiusX and radiusY, which means that touch shapes must have rigid
angles of 0 or 90 degrees.

What we have coming out of the Linux kernel is a touch angle and major
and minor axes lengths:

This would provide for any angle of touch input. I would like to suggest
following this approach and adding an angle parameter to touchpoints.
