13 * Creates a canvas object on which to draw.
14 * You must do this first, as all future calls to drawing methods
15 * from this instance will be bound to this canvas.
18 - container (HTMLElement|string) DOM element or it’s id which is going to be a parent for drawing surface
27 - all (array) (first 3 or 4 elements in the array are equal to [containerID, width, height] or [x, y, width, height]. The rest are element descriptions in format {type: type, <attributes>})
29 - onReadyCallback (function) function that is going to be called on DOM ready event. You can also subscribe to this event via Eve’s “DOMLoad” event. In this case method returns `undefined`.
