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]]
