[Vv] Landmarks bug in vv

[Benoît Presles]

Dear Thomas,

I have just performed some tests with the last commit of the master 
branch and unfortunately I am still experiencing some issues.
My tests are performed on the same image as before: when you add a 
landmark with the space bar I can now see the cross representing the 
landmark but its coordinates are wrong in the "landmarks panel".
It seems that it does not take into account the TransformMatrix from the 
image header.

Thanks for your help,
Best regards,
Ben
