public abstract class AbstractViewportManager extends Object
An AbstractViewportManager describes an element that occupies the whole rendering ICanvas or only a vertical slice of it. The AbstractViewportManager also provides a utility function for debugging the slices, that is the ability to display a 10*10 grid for checking the space occupied by the actual viewport definition.
