[Vv] Functionality of the fusion opacity slider

[David Sarrut]

Hello Shruti,

you are right, the fusion tool is buggy. If I remember well, it (almost)
works when the fusion image as pixel value in [0:1000]. We must rethink this
tools that was initially intended to display dose distribution on a CT image
and not really to fuse two images in a very general way. Could you please
indicate us for what kind of usage you want to use this tool ?

Sincerely,
David
