The previous calibrate script broke with an upgrade to
xserver-xorg-input-wacom 0.10.3+20100109-1. Here's a modified version
that works. Some changes:

    1. Calibration parameters are now saved to ~/.calibrate.X where X is
       the output of "xsetwacom get stylus Rotate". In old versions this
       used to be a number between 1 & 4. In new versions it seems to be
       one of NONE, CW, CCW, HALF.

    2. Resetting calibration broke with the upgrade. This is because the
       script used "xsetwacom getdefault" to find the tablet width /
       height. Looks like getdefault is not supported with the latest
       version of xsetwacom. Instead, I use the xyDefault property to
       reset parameters, and find the tablet width/height.
