 *  LEFT    - m_Left for left-hand pages, right-hand pages always empty.
 *            m_Left is a copy of master.
 *  ALL     - m_Master for right hand pages, m_Left for left hand pages.
 *          - m_Left is a copy of master.
 * MIRROR   - m_Master for right hand pages, m_Left for left hand pagers.
 *            m_Left is a copy of master, margins are mirrored.
 *
 * UI works exclusively on master! m_Left is adjusted on Chg at document
 * according to m_eUse.
 *
 * In order to simplify the work of the filters some more values are placed
 * into m_eUse:
 *
 * HEADERSHARE - Content of header is equal on left and right hand pages.
 * FOOTERSHARE - Content of footer is equal on left and right hand pages.
 *
 * The values are masked out in the respective getter and setter methods.
 * Access to complete m_eUse including the information on header and footer
 * via ReadUseOn(), WriteUseOn() (for Filter and CopyCTor)!
 *
 * The Frameformats for header/footer are adjusted by the UI according to
 * the attributes for header and footer at master (height, margin, back-
 * ground ...)
 * Header/footer for left hand pages are copied or mirrored (Chg at
 * document).
 * The respective attribute for content is cared for automatically on Chg at
 * document (contents are created or removed according to SHARE-information).
