Jeff Brown 037f727f49 Improve handling of size and orientation. ...

Some touch device drivers report the range of
ABS_MT_ORIENTATION as [0,1].  The Linux multitouch protocol
spec says that the 0 value should always be considered vertical.

Add a new 'box' calibration mode for size to handle the case
where width and height are being provided.  The 'diameter'
calibration mode is inadequate because it drops one of these
components.
