Overlay blocks like 'Seals' and 'Stamps' may optionally be password
protected. Password protected overlays will be invisible if the modified
timestamp of the parent graphics block changes. Such overlays will
be displayed or paper plotted only if they are authenticated. Only a user
with the correct password can revalidate.
