/**
 * 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
 *    ReactEventListener, 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.
 *

 *
 *   type := array|bool|func|object|number|string|oneOf([...])|instanceOf(...)
 *   decl := ReactPropTypes.{type}(.isRequired)?
 *
 * Each and every declaration produces a function with the same signature. This
 * allows the creation of custom validation functions. For example:
 *
 *  var MyLink = React.createClass({
 *    propTypes: {
 *      // An optional string or URI prop named "href".
 *      href: function(props, propName, componentName) {
 *        var propValue = props[propName];
 *        if (propValue != null && typeof propValue !== 'string' &&
 *            !(propValue instanceof URI)) {
 *          return new Error(
 *            'Expected a string or an URI for ' + propName + ' in ' +
 *            componentName
 *          );
 *        }
 *      }

 * is used to wrap several different methods. Wrappers are extremely simple -

 *   reconciliation takes place in a worker thread.
 * - Invoking any collected `componentDidUpdate` callbacks after rendering new

 * - (Future use case): Layout calculations before and after DOM updates.
