Abandoned members

[youngquan]

I have found that I can not use image.dimx() and visu.display() any more.
How can I know that some members has been abandoned ? And how can I get the members that have the same function?

I think these members have been dropped like ten years ago, so I'm a bit surprised :)
Anyway, visu.width(), visu.height(), visu.depth(), visu.spectrum() replace the (very) old
visu.dimx(), visu.dimy(), visu.dimz() and visu.dimc().

visu.display() is still working by the way.
