Return Value
True (the default) this TrayButton should be displayed. False, this TrayButton should be hidden
A TrayButton implementation can determine visibility based on the type of view within the current pane.
The tray will use this property at certain times, to determine if this TrayButton should be visible.
For a Map pane, this is a straightforward process - IsVisible will be used after the Pane is loaded.
For a Layout pane, IsVisible will also be used any time that a MapFrame is activated or deactivated.
