Instead of this, it'd be better to use the PointerKindMatcher to match all
PointerKind::TOUCH events. That should give us all touch-events that we care
about.

Done.

   EventFlagsMatcher? flags_matcher;
   // These flags will be stripped from incoming events' flags when comparing
   // against |flags_matcher|.
   EventFlagsMatcher? ignore_flags_matcher;
   KeyEventMatcher? key_matcher;
   PointerKindMatcher? pointer_kind_matcher;
   PointerLocationMatcher? pointer_location_matcher;
