Update Save scene from view

[LoicCadour]

We can currently save a scene directly from the view, but in this scene the vtk meshes have all the metadata we added recently.
Resulting eventually in a bad conversion of these meshes to CARTO.

In the pipeline we can export scenes in the right way at the very last step.

Let's homogenise with this latter way.

What do you mean: we need to remove the saving directly from the view? What kind of metadata are added?

[LoicCadour]

No, make the view use the "without-metaData" way.
The metaData are the one needed for the pipelines; there are many: SliceThickness, Orientation, ...
Export a vtk and open it in a text editor, you'll see many MUSIC metaData.

This issue is solved by https://github.com/Inria-Asclepios/music/pull/471 isn't it @LoicCadour ?

[LoicCadour]

No, this issue is about scene saving.
It's not a priority since, with the new Viewer, the scene saving will not be needed in the VT pipeline anymore.
But I think we should keep this issue open to remember that scene saving is still not homogenised.

[mathildemerle]

What i meant was that we differentiate the Carto and Scene buttons. Scene does not have to be valid for Carto. That's why i was saying that this issue is not relevant anymore with the PR :)

[LoicCadour]

Of course scenes still have to be valid for Carto.
The PR you quoted can be used for treating patient in Bordeaux, but in other centres, they still receive scenes; then they export in Carto with MUSIC Viewer.
