Ports all features except where JS interop is blocking us (declaration/path.js and instance/style.js). In particular, this has: // src/declaration/attributes.js // src/declaration/events.js // src/declaration/polymer-element.js // src/declaration/properties.js // src/declaration/prototype.js // src/declaration/styles.js // src/instance/attributes.js // src/instance/base.js // src/instance/events.js // src/instance/mdv.js // src/instance/properties.js // src/instance/utils.js // src/lib/deserialize.js // src/lib/job.js // src/lib/dom.js -- not needed in Dart // src/lib/lang.js -- not needed in Dart // src/lib/super.js -- not needed in Dart There's also a big architectural change: polymer-element data is now stored in the PolymerDeclaration class, which is separate from PolymerElement. This allows us to avoid duplicate work on every constructor, and should significantly speed up instance creation. All code is from the same revision: https://github.com/Polymer/polymer/blob/4dc481c11505991a7c43228d3797d28f21267779 The remaining unported files are for relatively minor features. "declaration/path.js" is for asset URL resolution, and we might have a Pub-based solution instead. "instance/style.js" has an opt-in, advanced style polyfill. It needs "ShadowCSS.shimPolyfillDirectives", and probably isn't too hard to make work in a follow up change. Other changes: * attributeChanged lifecycle method is implemented. * ObservableAnnotation is public so Polymer's @published can subclass it * bindProperty renamed to onPropertyChange to avoid conflict with Polymer member of the same name. * polymer/lib/boot.js preload's polymer-element and link[rel=stylesheet] R=blois@google.com Review URL: https://codereview.chromium.org//24149003 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@28134 260f80e4-7a28-3924-810f-c04153c831b5
