Events and interaction

• The basic event-handling, in diva.canvas.event, extends the AWT mouse-event handling to deal with floating-point coordinate systems and affine transforms.
• The interactor classes in diva.canvas.interactor, provide a slightly higher-level abstraction for handling events, as compared to the regular event listeners.
• Manipulators, in diva.canvas.manipulator, provide a pre-built set of mechanisms far attaching grab-handles to figure so that they can be resied and reshaped.
• Connectors, in diva.canvas.connector, provide a set of pre-built "connector" figures, that stay attached to figures on either end of them.
