* 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.
