127 * to query tablet for this missing information instead of hard coding in

133 *
134 * It also contains a digitizer application collection that also is not
135 * of interest since any information it contains would be duplicate
136 * of what is in wacom_features. Usually it defines a report of an array
137 * of bytes that could be used as max length of the stylus packet returned.
138 * If it happens to define a Digitizer-Stylus Physical Collection then
139 * the X and Y logical values contain valid data but it is ignored.
140 *
141 * A typical Interface Descriptor for a touch interface will contain a
142 * Digitizer-Finger Physical Collection which will define both logical
143 * X/Y maximum as well as the physical size of tablet. Since touch
144 * interfaces haven't supported pressure or distance, this is enough
145 * information to override invalid values in the wacom_features table.
