Input device calibration and capabilities.
Finished the input device capability API.
Added a mechanism for calibrating touch devices to obtain more
accurate information about the touch contact area.
Improved pointer location to show new coordinates and capabilities.

stutter very badly when more than a couple of fingers were down).
Added more diagnostics.
