// Defines the cordon tool. The cordon tool defines a rectangular
// volume that acts as a visibility filter. Only objects that intersect
// the cordon are rendered in the views. When saving the MAP file while
// the cordon tool is active, only brushes that intersect the cordon
// bounds are saved. The cordon box is replaced by brushes in order to
// seal the map.
