             *
             *  - 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.

             * 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

                 * An IndexedSourceMapConsumer instance represents a parsed source map which
                 * we can query for information. It differs from BasicSourceMapConsumer in
                 * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
                 * input.
                 *
                 * The only parameter is a raw source map (either as a JSON string, or already
                 * parsed to an object). According to the spec for indexed source maps, they
                 * have the following attributes:
                 *
                 *   - version: Which version of the source map spec this map is following.
                 *   - file: Optional. The generated file this source map is associated with.
                 *   - sections: A list of section definitions.
                 *
                 * Each value under the "sections" field has two fields:
                 *   - offset: The offset into the original specified at which this section
                 *       begins to apply, defined as an object with a "line" and "column"
                 *       field.
                 *   - map: A source map definition. This source map could also be indexed,
                 *       but doesn't have to be.
                 *
                 * Instead of the "map" field, it's also possible to have a "url" field
                 * specifying a URL to retrieve a source map from, but that's currently
                 * unsupported.

                 * Here's an example source map, taken from the source map spec[0], but
                 * modified to omit a section which uses the "url" field.
