FYI: It has been the case that not all the builders have recent XInput2
available so you might need to adjust this.

AFAIK, USE_XI2_MT flag switch on X2.1 and X2.0 is assumed by default in TouchUI
build, and code in this file is compliant with X2.0, hence I guess there is no
need to adjust..Plz let me know If I quoted wrong things...

This header is also being used in ui/base/x/events_x.cc, without any especial
flag.

Though XInput.h is redundant..
