feedback on 3D viewer from Frank 1/27/26

1. I think it would be good, to have the MATLAB design_arena.m script in the webtools repo, even if it was available somewhere else. That would make it stand by itself.
2. Also, aren't the G4 also using rectangular LEDs?
3. and grating for G4.1 CCW looks weird

[mbreiser]

for 1) consider linking to maDisplayTools repo
for 2) yes G4 should change to rectangles (but also consider allowing LED style to change to circles or squares if easier to visualise / better for screen shots)

for 3) not sure about that error, but maybe don't fix now if will change to show real patterns
