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