Yes, images alone are not of much use. I have been thinking about
integration possibilities during the last week. We should try to come
up with an evolutionary path to integrate things. For now,
DataAccessor and PixelDereferenceAdaptors can happily live together
(you can apply an accessor to an adaptor, no problem). In the long
run, I´d like to apply some lessons learned from VIGRA. For example, I
would like a design that can be extended naturally to 3-dimensional
and higher dimensional images (a lot of algorithm reuse is possible
accross dimensions, if it is done right).

Best regards

PS. I´ll be away for a week and cannot follow the discussion closely.
