- * A typical Interface Descriptor for a touch interface will contain a

- * X/Y maximum as well as the physical size of tablet. Since touch
- * interfaces haven't supported pressure or distance, this is enough
- * information to override invalid values in the wacom_features table.

- * 3rd gen Bamboo Touch no longer define a Digitizer-Finger Pysical
