dix: when converting to XI 1.x events, use the first_valuator's device mode

Browse Source 
Don't stop processing events when a valuator's mode doesn't match the 0th
valuator's mode. Instead, start with the first_valuator in the event and
keep stacking them on until the first valuator with a different mode is hit.
