* InputEventOptions is used by nsContentUtils::DispatchInputEvent() to specify
* some attributes of InputEvent. It would be nice if this was in
* nsContentUtils.h, however, it needs to include StaticRange.h for declaring
* this. That would cause unnecessary dependency and makes incremental build
* slower when you touch StaticRange.h even though most nsContentUtils.h users
* don't use it. Therefore, this struct is declared in separated header file
* here.
