   * Optional parameter [quality] in the range of 0.0 and 1.0 can be used when requesting [type]

/**
 * Base class that supports listening for and dispatching browser events.
 *
 * Normally events are accessed via the Stream getter:
 *
 *     element.onMouseOver.listen((e) => print('Mouse over!'));
 *
 * To access bubbling events which are declared on one element, but may bubble
 * up to another element type (common for MediaElement events):
 *
 *     MediaElement.pauseEvent.forTarget(document.body).listen(...);
 *
 * To useCapture on events:
 *
 *     Element.keyDownEvent.forTarget(element, useCapture: true).listen(...);
 *
 * Custom events can be declared as:
 *
 *    class DataGenerator {
 *      static EventStreamProvider<Event> dataEvent =
 *          new EventStreamProvider('data');
 *    }
 *
 * Then listeners should access the event with:

 *
 * Custom events can also be accessed as:
 *
 *     element.on['some_event'].listen(...);
 *

/**
 * A utility for retrieving data from a URL.
 *
 * HttpRequest can be used to obtain data from http, ftp, and file
 * protocols.
 *
 * For example, suppose we're developing these API docs, and we
 * wish to retrieve the HTML of the top-level page and print it out.
 * The easiest way to do that would be:
 *
 *     HttpRequest.getString('http://api.dartlang.org').then((response) {
 *       print(response);
 *     });
 *
 * **Important**: With the default behavior of this class, your
 * code making the request should be served from the same origin (domain name,
 * port, and application layer protocol) as the URL you are trying to access
 * with HttpRequest. However, there are ways to
 * [get around this restriction](http://www.dartlang.org/articles/json-web-service/#note-on-jsonp).
 *
 * See also:
 *
 * * [Dart article on using HttpRequests](http://www.dartlang.org/articles/json-web-service/#getting-data)
 * * [JS XMLHttpRequest](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest)

   * * If `Access-Control-Expose-Headers` has not been set to true, only a subset of all the response headers will be returned when calling [getAllRequestHeaders].
   *
   * Note that requests for file:// URIs are only supported by Chrome extensions

   * will also never fail- the Future will always complete successfully, even

/**
 * The type used by the
 * [Window.localStorage] and [Window.sessionStorage] properties.
 * Storage is implemented as a Map&lt;String, String>.
 *
 * To store and get values, use Dart's built-in map syntax:
 *
 *     window.localStorage['key1'] = 'val1';
 *     window.localStorage['key2'] = 'val2';
 *     window.localStorage['key3'] = 'val3';
 *     assert(window.localStorage['key3'] == 'val3');
 *
 * You can use [Map](http://api.dartlang.org/dart_core/Map.html) APIs
 * such as containsValue(), clear(), and length:
 *
 *     assert(window.localStorage.containsValue('does not exist') == false);
 *     window.localStorage.clear();
 *     assert(window.localStorage.length == 0);
 *
 * For more examples of using this API, see
 * [localstorage_test.dart](http://code.google.com/p/dart/source/browse/branches/bleeding_edge/dart/tests/html/localstorage_test.dart).
 * For details on using the Map API, see the

// This code is inspired by ChangeSummary:
// https://github.com/rafaelw/ChangeSummary/blob/master/change_summary.js
// ...which underlies MDV. Since we don't need the functionality of
// ChangeSummary, we just implement what we need for data bindings.
// This allows our implementation to be much simpler.

// TODO(jmesserly): should we make these types stronger, and require
// Observable objects? Currently, it is fine to say something like:
//     var path = new PathObserver(123, '');
//     print(path.value); // "123"
//
// Furthermore this degenerate case is allowed:
//     var path = new PathObserver(123, 'foo.bar.baz.qux');
//     print(path.value); // "null"
//
// Here we see that any invalid (i.e. not Observable) value will break the
// path chain without producing an error or exception.
//
// Now the real question: should we do this? For the former case, the behavior
// is correct but we could chose to handle it in the dart:html bindings layer.
// For the latter case, it might be better to throw an error so users can find
// the problem.
