0023282: Wrong triangulation on cone
For cone with angle from around 90 to 180 the produced triangulation is wrong, see screenshots.
The issue is reproduced with versions 6.5.0-6.5.3.
If to specify an angle 181 (in the DRAW reproducer) then the triangulation is correct.
pcone p 50 0 100 18
#pcone p 50 0 100 90 - is also bad
#pcone p 50 0 100 181 - is fine
