/**
 * The #GtkHandleBox widget allows a portion of a window to be "torn
 * off". It is a bin widget which displays its child and a handle that
 * the user can drag to tear off a separate window (the “float
 * window”) containing the child widget. A thin
 * “ghost” is drawn in the original location of the
 * handlebox. By dragging the separate window back to its original
 * location, it can be reattached.
 * 
 * When reattaching, the ghost and float window, must be aligned
 * along one of the edges, the “snap edge”.
 * This either can be specified by the application programmer
 * explicitly, or GTK+ will pick a reasonable default based
 * on the handle position.
 * 
 * To make detaching and reattaching the handlebox as minimally confusing
 * as possible to the user, it is important to set the snap edge so that
 * the snap edge does not move when the handlebox is deattached. For
 * instance, if the handlebox is packed at the bottom of a VBox, then
 * when the handlebox is detached, the bottom edge of the handlebox's
 * allocation will remain fixed as the height of the handlebox shrinks,
 * so the snap edge should be set to %GTK_POS_BOTTOM.
 * 
 * > #GtkHandleBox has been deprecated. It is very specialized, lacks features
 * > to make it useful and most importantly does not fit well into modern
 * > application design. Do not use it. There is no replacement.
