Hi Albert,

FlatIterationOrder also is defined with respect to the Interval of the 
image.  Two images only have equal iteration order, when they have the
same number of dimensions, the same size, and the same minimum. The idea
is that you could at any point localize Cursors that you move in unison
through two compatible images and they would give you the same location.

A 3D and a 2D image never have the same iteration order.

So a singleton will not work.

best regards,
Tobias
