 *
 * A single EntryBuffer object can be shared by multiple Entry
 * widgets which will then share the same text content, but not the cursor
 * position, visibility attributes, icon etc.
 *
 * EntryBuffer may be derived from. Such a derived class might allow
 * text to be stored in an alternate location, such as non-pageable memory,
 * useful in the case of important passwords. Or a derived class could
 * integrate with an application's concept of undo/redo.
