/* hoping that since wacom says if LOGCONTEXT.lcData fields are set, then the ones
 * not available will be ignored. wouldnt be nice to have to parse this.
 * plus it's optimising to not have jna instantiate a new class for all of the members
 * of this struct for every PACKETEXT.
 * i also assume that if the wacom "driver's" wintab implementation supports
 * EXPKEYSDATA, TOUCHSTRIP and TOUCHRING, the driver doesn't bother to fail on wtopen
 * even if the requested tablet(ID) doesn't support them.
 * as they say: "insert quote here about the PACKETDATA not
 * supported items doesn't seem to fail"
