abstractGraphic

A Graphic is the base Excalibur primitive for something that can be drawn to the ExcaliburGraphicsContext. Sprite, Animation, GraphicsGroup, Canvas, Rectangle, Circle, and Polygon all derive from the Graphic abstract class.

Implementors of a Graphic must override the abstract Graphic._drawImage method to render an image to the graphics context. Graphic handles all the position, rotation, and scale transformations in Graphic._preDraw and Graphic._postDraw
