/*
 * This file provides Gtk implementations of the mozilla Generating Key Pair
 * dialogs.
 *
 * This implementation takes some liberties with the mozilla API. Although the
 * API requires a nsIDomWindowInternal, it only actually calls the Close()
 * function on that class. Therefore we provide a dummy class that only 
 * implements that function (it just sets a flag). 
 *
 * Periodically we check to see whether the dialog should have been closed. If
 * it should be closed, then the key generation has finished, so close the dialog
 * (using gtk_dialog_response), and return.
