beamChain breaks on horizontal/vertical segments

[lopisan]

Hi,
I've found that beamChain breaks on horizontal and vertical segments of polyline:

When eps is non-zero, it does work:

a=10;
eps=1e-6;
points=[[0, 0, 0], [0+eps, a, 0], [a, a+eps, 0]];
polygon(polyRound( beamChain(points, offset1=1, offset2=-1), 30));

but when eps=0 it breaks (doesn't show anything and sometimes - not always throw a undef error):

a=10;
eps=0;
points=[[0, 0, 0], [0+eps, a, 0], [a, a+eps, 0]];
polygon(polyRound( beamChain(points, offset1=1, offset2=-1), 30));

PS: Thanks for the great library I'm starting with OpenSCAD and I like polyRound very much.

Hey @lopisan,
Thanks for reporting this bug.
Just wanted to let you know I'm busy the weekend, hopefully, I'll get to this early next week.

There's some documentation updates I need to do for beam chain anyway #11, so good extra prompt to get to it.

Glad you like the library 🤗

Hey @lopisan,
Thanks again for pointing this out, and a well-written bug report.
This should be resolved now, please use the latest version of the code.

Let me know if you have any more issues, or if there's any way I can help you.

Cheers,
Kurt.
