-/**
-  Helper class for tracking the pointer ids for each type of PointerEvents.
-  Using id re-mapping at this layer, this class makes sure that regardless of the
-  domain of the id (i.e. in touch or pen) the corresponding pointer event will have
-  a unique id amongst all pointer events as per pointer events' specification.
-  This class intended to behave the same as existing browsers as much as possible
-  for compatibility reasons. Particularly it behaves very similar to MS Edge to have
-  pointer event ids generated by mouse always equal 1 and those that are generated
-  by touch and pen will have increasing ids from 2.
