Periodicity of the shape means that the shape can be repeated in any periodic direction any number of times without creation of the new geometry or splits.
The idea of this algorithm is to make the shape look similarly on the opposite sides or on the period bounds of periodic directions.
It does not mean that the opposite sides of the shape will be mirrored. It just means the the opposite sides of the shape should be split by each other and obtain the same geometry on opposite sides.
Such approach will allow repeating the shape, i.e. translating the copy of a shape on the period, without creation of new geometry because there will be no coinciding parts of different dimension.

Implementation of capturing of output to standard streams in DRAW (see command dlog) is revised to avoid problems with command "test" executing long test scripts:

2. In Draw_Window.cxx the standard Tcl channels are initialized manually using corrected version of Tcl internal function. This works around a problem with Tcl channels on Windows being bound to OS device handle owned by the system which can get invalidated as result of calls to dup2() (used to capture output to standard streams).

0030354: BOP Cut doesn't modify the attached face
The reason of this problem is in wrong work of classifier algorithm (see the message ~
0080992 to the issue #30354). Therefore, the algorithm of IntTools_FClass2d class has been improved. Namely, now orientation of the polygon is computed from area-criterion instead of angle. As result, some simplification of the method IntTools_FClass2d::Init(...) has been made.
<!break>
1. New constructor has been added to the class CSLib_Class2d. It allows applying TColgp_SequenceOfPnt2d.
2. DRAW-commands "addpolygonnode" and "polygonprops" have been created. They are covered by the test case "tests/geometry/2dpolygon/A1".
3. New method Poly::PolygonProperties(...) has been created. See help for detailed information.
4. New testgrid "lowalgos classifier" has been created.

Split seam edge of a cone according to the specified parameters.
Seam edge functor is called before check of triangulation consistency in order to keep face status consistent.
The cause is that split seam edge can set Outdated flag when Reused is set by another functor without reset which can lead to refusement of such face by triangulation procedure.
