CAM/Profile losing segments

[slazav]

For certain shapes CAM/Profile produces wrong result (see screenshot). I'm using recent version 0.9.16. I think, it happens when a perpendicular segment with length = mill radius appears. For this test D=0.2mm mill is used.

Test DXF file cut_test.dxf.txt, to be used with D0.2mm mill

I believe the problem arises from the following: intersectSelf() correctly generates the segments. The error seems to be in the assignment of mark as _cross for later evaluation in removeExclude().
