The graphical appearance of a Morph may be any shape e.g. circle, oval, star, scribble, etc. In order to facilitate a morph's 2-d spatial positioning, every morph has, to a first approximation, a rectangular shape and position represented by the value of the instance variable #bounds which encompasses every point that describes the morph's shape. Because a morph may also contain submorphs which have boundaries that lie outside of the morph's bounds, each morph also has an instance variable #fullBounds which is represented by a rectangle which encompasses every point which describes the morph and every submorph chained below it.
