147 * for touch interfaces has pretty complete data, this function exists
148 * to query tablet for this missing information instead of hard coding in

151 * A typical Interface Descriptor for a stylus will contain a

153 * function will ignore it.
155 * It also contains a digitizer application collection that also is not
156 * of interest since any information it contains would be duplicate
157 * of what is in wacom_features. Usually it defines a report of an array
158 * of bytes that could be used as max length of the stylus packet returned.
159 * If it happens to define a Digitizer-Stylus Physical Collection then
160 * the X and Y logical values contain valid data but it is ignored.

163 * Digitizer-Finger Physical Collection which will define both logical
164 * X/Y maximum as well as the physical size of tablet. Since touch
