I personally think, that the reference image is anyway often of very limited
use for animation tests. Animation tests I create typically do not rely on
reference images and several of them try to be selfconsistent, indicating
at least typical errors of the tested feature in an easy way even for
smaller deviations. But this is not completely trivial to have for any 
feature to be tested and for many things tested it is not really necessary
to have a precision test. As here the timing of the marker is not centered,
therefore it is only a help to get a rough impression of the timing - it is
already much better than to have no indication at all ;o)

And for example if you have animations with repeatDur="indefinite"
obviously there is not reference image for the 'final' display typically
and the PNG shows something different. And if the animation is not
frozen with an interesting value, obviously the PNG for the final
state is not very informative at all ;o)

Well for this test it is the intention of some subtests to test the 
behaviour of use, therefore it should be no complication to reuse
the markers.
