Viewer3D causes VisNow to crash after multiple image saves
Create viewer 3d, connect anything, and save resulting image multiple times. On fresh VisNow with one viewer 3d, after 31 saved images VisNow will crash. If you have used this VN run before or you already have multiple viewers open, it will crash sooner.
The technical reason is the limitation of JOGL on Java3D to create only 32 instances of Canvas3D. And VN is creating one Canvas3D for each viewer 3d, and one Canvas3D for each off screen rendering required to save an image.
