130 *
131 * A typical Interface Descriptor for a stylus will contain a

135 * It also contains a digitizer application collection that also is not
136 * of interest since any information it contains would be duplicate
137 * of what is in wacom_features. Usually it defines a report of an array
138 * of bytes that could be used as max length of the stylus packet returned.
139 * If it happens to define a Digitizer-Stylus Physical Collection then
140 * the X and Y logical values contain valid data but it is ignored.
141 *
142 * A typical Interface Descriptor for a touch interface will contain a
143 * Digitizer-Finger Physical Collection which will define both logical
144 * X/Y maximum as well as the physical size of tablet. Since touch
145 * interfaces haven't supported pressure or distance, this is enough
146 * information to override invalid values in the wacom_features table.
