Bug 1462784 - Remove EVENTS category. r=njn Categories are useful to indicate: This much % of time was spent in this category. The EVENTS category isn't a very good match for this. This category is currently only set on labels of functions that handle the processing of an event. But those functions are usually closer to the base of the stack, and the actual CPU work during the processing of an event is usually in another category closer to the top of the stack, e.g. in JS if we're running an event handler, or in LAYOUT if we're hit testing the position of the event. This changeset removes the EVENTS category and replaces all uses of it with the OTHER category. MozReview-Commit-ID: JPm5hQiBkvp
