<DD>texture Attribute has been applied externally,
and therefore this attribute type has been dirtied

note, if you have an osg::StateAttribute which you have applied externally
then use the have_applied(attribute) method as this will the osg::State to
track the current state more accuratly and enable lazy state updating such
that only changed state will be applied.
