[chimerax-users] Render images in nogui mode

[Tom Goddard]

I have fixed the bug where opening a map in ChimeraX in nogui mode raises an error. It was trying to show the volume viewer gui interface.  This does not fix the problem that offscreen rendering is not working in nogui mode noted in this bug report
