Closed Bug 1420516 Opened 2 years ago Closed 2 years ago
Splitting this out from bug 951793. Removing ScrollDirection::NONE allows us to be more precise about whether or not "no scroll direction" is a valid value for a variable. In cases where it is, Maybe<ScrollDirection> is used as the variable's type. It also facilitates using an EnumSet<ScrollDirection> to represent a set of allowed scroll directions.
