/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactDOMEventListener, which is injected and can therefore support
* pluggable event sources. This is the only work that occurs in the main
* thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.
*

* We listen for bubbled touch events on the document object.
*
* Firefox v8.01 (and possibly others) exhibited strange behavior when
* mounting `onmousemove` events at some node that was not the document
* element. The symptoms were that if your mouse is not moving over something
* contained within that mount point (for example on the background) the
* top-level listeners for `onmousemove` won't be called. However, if you
* register the `mousemove` on the document object, then it will of course
* catch all `mousemove`s. This along with iOS quirks, justifies restricting
* top-level listeners to the document object only, at least for these
* movement types of events and possibly all events.
*
* @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

* Also, `keyup`/`keypress`/`keydown` do not bubble to the window on IE, but

* becomes .style.font = ''
* Removing a longhand property (should revert to shorthand; doesn't):
* {font: 'foo', fontVariant: 'bar'} -> {font: 'foo'}
* becomes .style.fontVariant = ''

// UpdateQueue is a linked list of prioritized updates.
//
// Like fibers, update queues come in pairs: a current queue, which represents
// the visible state of the screen, and a work-in-progress queue, which can be
// mutated and processed asynchronously before it is committed — a form of
// double buffering. If a work-in-progress render is discarded before finishing,
// we create a new work-in-progress by cloning the current queue.
//
// Both queues share a persistent, singly-linked list structure. To schedule an
// update, we append it to the end of both queues. Each queue maintains a
// pointer to first update in the persistent list that hasn't been processed.
// The work-in-progress pointer always has a position equal to or greater than
// the current queue, since we always work on that one. The current queue's
// pointer is only updated during the commit phase, when we swap in the
// work-in-progress.
//
// For example:
//
// Current pointer: A - B - C - D - E - F
// Work-in-progress pointer: D - E - F
// ^
// The work-in-progress queue has
// processed more updates than current.
//
// The reason we append to both queues is because otherwise we might drop
// updates without ever processing them. For example, if we only add updates to
// the work-in-progress queue, some updates could be lost whenever a work-in
// -progress render restarts by cloning from current. Similarly, if we only add
// updates to the current queue, the updates will be lost whenever an already
// in-progress queue commits and swaps with the current queue. However, by
// adding to both queues, we guarantee that the update will be part of the next
// work-in-progress. (And because the work-in-progress queue becomes the
// current queue once it commits, there's no danger of applying the same
// update twice.)
//
// Prioritization
// --------------
//
// Updates are not sorted by priority, but by insertion; new updates are always
// appended to the end of the list.
//
// The priority is still important, though. When processing the update queue
// during the render phase, only the updates with sufficient priority are
// included in the result. If we skip an update because it has insufficient
// priority, it remains in the queue to be processed later, during a lower
// priority render. Crucially, all updates subsequent to a skipped update also
// remain in the queue *regardless of their priority*. That means high priority
// updates are sometimes processed twice, at two separate priorities. We also
// keep track of a base state, that represents the state before the first
// update in the queue is applied.
//
// For example:
//
// Given a base state of '', and the following queue of updates
//
// A1 - B2 - C1 - D2
//
// where the number indicates the priority, and the update is applied to the
// previous state by appending a letter, React will process these updates as
// two separate renders, one per distinct priority level:
//
// First render, at priority 1:
// Base state: ''
// Updates: [A1, C1]
// Result state: 'AC'
//
// Second render, at priority 2:
// Base state: 'A' <- The base state does not include C1,
// because B2 was skipped.
// Updates: [B2, C1, D2] <- C1 was rebased on top of B2
// Result state: 'ABCD'
//
// Because we process updates in insertion order, and rebase high priority
// updates when preceding updates are skipped, the final result is deterministic
// regardless of priority. Intermediate state may vary according to system
// resources, but the final state is always the same.
