This is a backwards-compatibility option similar to the Pressure2K
option. GDK2 applications are effectively limited to 7 axes
(value of GDK_AXES_LAST in GDK2) and adding smooth panscrolling gives
our device 8 axes total. This can cause issues when the driver, GDK and
the application don't agree on the number of axes in the device.
This is an application/GDK bug but as for the Pressure2K option we
expect there to be applications that cannot be updated easily. To work
around this, provide a driver option to disable this new feature
altogether and effectively return to 6 axes for the pen device.

This is a partial revert of https://github.com/linuxwacom/xf86-input-wacom/commit/fe923e927a8ddf4d2e82ef4757c885b06d47fa03 "Implement smooth panscrolling" for the implementation. Minor changes though, the implementation now relies more on local variables than pointers.
This is in response to #307, Gimp crashing with xf86-input-wacom 1.2.0 because we now have 8 axes on the pen.

Note: not fully tested yet, just throwing this out as FYI and so there's no duplication of effort.
