doMouseWheel method

void doMouseWheel()

The diagram will call this method as the mouse wheel is rotated. Implementations of this method can look at Diagram#lastInput to get the mouse event and input state.

By default this method does nothing. (But the ToolManager#doMouseWheel override will call Tool#standardMouseWheel.) This method may be overridden. Please read the Introduction page on Extensions for how to override methods and how to call this base method. @expose
