Problem with LDView primitive substitution

[Philippe Hurbain]

It seems that primitive substitution doesn't work on some hires cones. Case in point, 48\1-4con19 used in this part: https://www.ldraw.org/cgi-bin/ptdetail.c...s/2745.dat
At high substitution levels cone no longer matches cylinder.
This concerns all LDView versions I could test, from 4.1 to 4.4.1beta2

I observed a similar thing back in 2016.

Conclusion was that a certain combination of options led to the display issue.

Clearly the same problem. 48\ cone primitives are neither substituted nor smoothed for radius >= 10, though it works fine for normal res. Substitution is correctly done for rings.

I'll investigate. I think my filename parsing is broken for the 48 cones with a 2-digit size.
