(graphics): deprecate VTK
Description
Most of our applications switched to Ogre3D. QT3D is likely to supersede him in the future. We will not be able to maintain 3 backends, and this is pointless anyway.
Task list
-
Deprecate fwRenderVTK::SRender, this should be enough to warn the user -
Replace VTK generic scene by Ogre generic scene in Sight applications
