/**
*  PURPOSE:
*
*  Central definitions of shared objects and constants, global tool functions.
*
*  - All menu codes used in the program (MENU_...)
*  - Global tool functions for handling collections, base types, projection
*    strings, X events, ... . See ``Global functions''.
*  - rviewFrame class which must be the base class of all frames used in rView.
*  - rviewFrameMgr class for handling all of rView's frames (dispatching events
*    etc)
*  - rviewMultiline class for displaying several lines of non-editable text.
*  - rviewDialog class which is the base class for all rView's dialog windows.
*  - rviewErrorbox class, derived from rviewDialog.
*  - rviewProgress class, derived from rviewDialog.
*  - rviewResults class for displaying database results and dispatching object
*    viewers. Relies on code provided by rviewMDD for scaling/resampling/endian
*    conversions.
*  - rviewAbout class for displaying information about rView itself.
*  - rviewStringSet class for displaying a set of strings in a scrollable
*    list box.
