[Chimera-users] Gaussian blur depth cueing? (ChimeraX)

Sort of related to this - any chance for symmetric depth cueing as an option in ChimeraX? 

So that instead of intensity falloff being linear from the front clip plane to the back clip plane, it is triangular - intensity linearly increasing from the front clip plane to the midpoint, then decreasing towards the back clip plane? 

This would be helpful when making closeup clipped images of models with maps, where fragments of regions in front of the region of interest can obscure the intended subject, which is somewhat distracting.

Cheers
