Extends mxEventSource to implement a view for a graph. This class is in charge of computing the absolute coordinates for the relative child geometries, the points for perimeters and edge styles and keeping them cached in mxCellStates for faster retrieval. The states are updated whenever the model or the view state (translate, scale) changes. The scale and translate are honoured in the bounds.
