- simplified Renderer(s) architecture (removed decorator, CachedFrameRenderer simply inherits from FrameRenderer now) - keeping AbstractRenderer to act as interface - fixed issue with layers : forgot to clone the first frame while merging and therefore was modifying the original frame when I just wanted to create a tmp frame (FrameUtils.js) - extracted the mousemove throttling delay used in DrawingController to Constants.js and reduced it from 40ms to 10ms
