Thickness for constellation lines not working

[Atlan]

I tried to set the thickness for "View/Starlore/Show lines with thickness" manually and with scripts. The option never works when set from the options window. I've seen it work once or twice (out of 100) with script, but I can't reproduce it.

Looking at the log, I realize that I was using the ANGLE Version. Checked the issue with the standard version: Line thickness works manual and scripted.

This is out of our control, sorry.

Line width is notoriously not working well depending on drivers.

At some point we'll need to re-code the line drawing functions using a texture or something similar allowing to set a precise depth
