Scrawl-canvas v8 - Canvas test 001

Block and wheel entitys (make, clone, method)
Drag and drop block and wheel entitys

Test purpose

Create block and wheel entitys
Clone the entitys
Position the entitys on the canvas
Change the state of a subset of entitys sharing the same state object
Check the various drawing methods available to the entitys
Check that the 'purge' attribute has removed all non-essential path, pivot, mimic and filter attributes from Wheel entitys

Check that when a drag operation starts, the dragged entity does not suddenly jump
Check that when a drag operation ends, the dragged entity does not suddenly jump

Kill and resurrect several entitys to make sure they remove themselves entirely from the Scrawl-canvas system, and cleanly recreate themselves from saved packets

Note that this demo runs on the minified library, not on the source code!
