Suggest "Returns true if the InputInjector returned by Create() supports
InjectTouchEvent() on this platform."

[Rintaro Kuroiwa, 2015/04/22 19:55:59]

Done.

+  static bool CanInjectTouch();

[Wez, 2015/04/21 02:12:12]

nit: We typically name these in the style SupportsTouchEvents() or
SupportsInjectTouchEvent().

[Rintaro Kuroiwa, 2015/04/22 19:55:59]

Will go with SupportsRawTouchEvents().
