/*
 * GUI front-end preference header
 *
 * Preference(also referred to as property) policy:
 * There is one global prefernece variable, g_pref.
 * At startup, g_pref is load from ~/.gnome/gtkdiff file.
 * Each instance, such as window and view, has a copy of its own preference,
 * and g_pref is used as the default value of its copy.
 * When a user modifies any preference, the preference-copy of
 * the current view is modified, and g_pref is also modified simultaneously.
 * At quiting, g_pref is saved into ~/.gnome/gtkdiff file.
 *
 * I'm providing two UIs, menubar and property-box.
 * Color setting is through property-box, and the others are through menus.
 * The reason is that I believe menu is a better UI than property-box.
