such as Bamboo; some multi-interface devices do not support touch at all,
such as Pen only Intuos5. Make sure we report the right device names.

Scale up touch width and height values for Intuos Pro

The width and height values reported by the Intuos Pro are not in
surface units as required by the MT protocol. A simple multiplier

Make sure touch_max is set for touch devices

Old single touch Tablet PCs do not have touch_max set at
wacom_features. Since touch device at lease supports one
finger, assign touch_max to 1 when touch usage is defined
in its HID Descriptor and touch_max is not pre-defined.

data on/off. The state of the switch is reported periodically
from the tablet. To report the state the driver will emit SW_MUTE_DEVICE
events.
