[Vv] Modifying landmarks

[David Sarrut]

Hello Bilal,

your are right, the current landmarks management is not really good in vv.
A solution would be to associated an ID to each landmark, allowing to
manage each of them separately. Also, the supported file format could be
enhanced. This is not really hard to do, but it takes times and,
unfortunately, there is no development time planned for that part
currently.

However, as this is open-source, you can give it a try (start with
files vvLandmarks.h/cxx and vvLandmarksPanel.h.cxx). If you feel you can
work on that, do not hesitate !

Sincerely,
David
