+ * Creates a new #GtkWindow, which is a toplevel window that can

+ * popup menu from scratch (which is a bad idea, just use #GtkMenu),
+ * you might use #GTK_WINDOW_POPUP. #GTK_WINDOW_POPUP is not for

+ * In GTK+, #GTK_WINDOW_POPUP means a pop-up menu or pop-up tooltip.
+ * Popup windows are not controlled by the window manager.
+ *
+ * If you simply want an undecorated window (no window borders), use
+ * gtk_window_set_decorated(), don't use #GTK_WINDOW_POPUP.
+ *
+ * Return value: a new #GtkWindow.
