- makes the event logic not involve a boolean return value (since we ignored it anyway) - splits the event handling logic into two steps, hit testing and event dispatch - introduces an App class on the Dart side to factor out the interaction with the C++ side - ports sector-layout and simple_render_tree to the new App infrastructure - port simple_render_tree to the new event handling logic - implement hit testing for the sector-layout demo R=eseidel@chromium.org Review URL: https://codereview.chromium.org/1143343004
