this builds on top of #862, i'm pushing this just as a draft to demonstrate the feasibility of combining volume rendering and segmentation layers once we have a segment properties shader that unifies the coloring across all the views.

here's an example rendering that you can make of dense synapses colored by their IDs..

Thanks for putting this together and sharing the really nice images @fcollman! This looks cool, and would be a good way to see segmentation in 3D without requiring to have meshes or skeletons. I must admit I'm also glad to see the image volume rendering can be extended with pretty minimal changes in the volume rendering file itself

example with Janelia'as flyem_fib-25

Trying to bump up the resolution, got some very good looking results but easily overwhelmed my machine
