Description of the bug The geometry is composed of two large rooms connected by a channel of width 3.5 meters. The GeometryBuilder fails with this error:

Assertion failed: 0, file C:\Users\coue_be\Dev\vcpkg\buildtrees\poly2tri\src\bd85c3c204-6194be63e9.clean\poly2tri\sweep\sweep.cc, line 770

After consulting the source file above, the issue may be related to the orientation of the polygons.

Expected behavior Apart from possible numerical issues linked to floating-point numbers, the sweeping algorithm should work: it works with widths of 3 meters and 4 meters but not 3.5.

Additional context Here is the geometry which can be visualized with this Python script (with the trajectory part to be commented out).

@bcoueraud87 Can you please retest this with the latest version on SUMO-Integration? I am unable to reproduce the observed behaviour with the geometry you provided.
