“add segment index” button for volume annotations that don’t have one

[fm3]

Similar to the downsample button, this would internally use the duplicate route and replace the tracing id in the annotation layer.

Would need a new route on webknossos backend side that forwards this to tracingstore (should be quick to do)

Note that this is currently only possible for volume annotations with no fallback segmentation layer

unassigning myself as the backend part is done

Is there a way to know whether a volume tracing has a segment index?

@MichaelBuessemeyer This is probably quick to do and could be something for you in this sprint. I imagine an entry in the layer dropdown.

Yes, see VolumeTracing.proto, optional bool hasSegmentIndex
