Remove Scroller and add TileFiller
Merge branch 'dev'
Some correction on the scrolling image sample : no need to explicitly ask the update of a display object, it updates automaticly once it's added to the display list. Don't set a fixed fps for html5 target and use RAF instead, much smoother (application.xml, use unless="html5" when setting fps=60)
enbling depth testing did not impact perf in a bad way finally.

removed update method from displayObject. DisplayObject are for display and should'n have logic in them. Later the engine will be separated into several system and thread and having each class doing it's only purpose will help a lot.
changed version: removing update from display object will create incompatibility. user now have to update manually each game object.
