/**
 * This is the Model and a Controller for panel editor Views. (Panel Editor,
 * Layout Editor or any subsequent editors) The Model is simply a list of
 * Positionable objects added to a "target panel". Control of the display
 * attributes of the Positionable objects is done here. However, control of
 * mouse events is passed to the editor views, so control is also done by the
 * editor views.
 * <p>
 * The "contents" List keeps track of all the objects added to the target frame
 * for later manipulation. This class only locates and moves "target panel"
 * items, and does not control their appearance - that is left for the editor
 * views.
 * <p>
 * The Editor has tri-state "flags" to control the display of Positionable
 * object attributes globally - i.e. "on" or "off" for all - or as a third
 * state, permits the display control "locally" by corresponding flags in each
 * Positionable object
 * <p>
 * The title of the target and the editor panel are kept consistent via the
 * {#setTitle} method.
 * <p>
 * Mouse events are initial handled here, rather than in the individual
 * displayed objects, so that selection boxes for moving multiple objects can be
 * provided.
 * <p>
 * This class also implements an effective ToolTipManager replacement, because
 * the standard Swing one can't deal with the coordinate changes used to zoom a
 * panel. It works by controlling the contents of the _tooltip instance
 * variable, and triggering repaint of the target window when the tooltip
 * changes. The window painting then explicitly draws the tooltip for the
 * underlying object.
