0027620: Test perf bop boxholes crashes DRAW

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:

1. Method OSD_File::Capture() is removed: on Windows it was allocating a C file descriptor for a file opened using WinAPI, and never released that descriptor (once allocated, it cannot be released separately from WinAPI file handle). Direct calls to dup/dup2 are used instead.

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).

3. Temporary file for capturing is opened once and used to store whole log, thus the need to collect log in the string stream in memory is avoided

4. Possible errors of dup() and dup2() are checked and reported

Test demo draw dlog is added

Off-topic changes:

- Test demo draw getsource is corrected for VS2017 which generates file name in lowercase
- Field myFaceBounds is initialized in constructor of the class BRepAlgo_NormalProjection to avoid undefined behavior
- Test bugs modalg_5 bug24012 is corrected to use command nproject instead of custom one, and to check propertes of the resulting shape

0028828: Modeling Algorithms - New functionalities of BRepFilletAPI_MakeChamfer algorithm

Two new functionalities have been added in BRepFilletAPI_MakeChamfer:
- constant throat (the section of chamfer is isosceles triangle, its height is constant in all sections - this is the "throat" of the weld);
- constant throat with penetration(the section of chamfer is right-angled triangle, the first of two surfaces (where is the top of the chamfer) is virtually moved inside the solid by offset operation, the apex of the section is on the intersection curve between moved surface and second surface, right angle is at the top of the chamfer, the length of the leg from apex to top is constant - this is the "throat" of the weld).

- New abstract classes BlendFunc_GenChamfer and BlendFunc_GenChamfInv have been added;
- Class BlendFunc_Chamfer is now descended from BlendFunc_GenChamfer, class BlendFunc_ChamfInv is now descended from BlendFunc_GenChamfInv.
- New class BlendFunc_ConstThroat is descended from BlendFunc_GenChamfer, new class BlendFund_ConstThroatInv is descended from BlendFunc_GenChamfInv.
- New class BlendFunc_ConstThroatWithPenetration is descended from BlendFunc_GenChamfer, new class BlendFund_ConstThroatWithPenetrationInv is descended from BlendFunc_GenChamfInv.
- Class ChFi3d_ChBuilder has now mode of chamfer that can be ClassicChamfer, ConstThroatChamfer and ConstThroatWithPenetrationChamfer.
- Two new DRAW Test Harness commands "chamf_throat" ant "chamf_throat_with_penetration" have been added for the second mode of ChBuilder.
- The interface of DRAW Test Harness command "chamf" changed for symmetric case.

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.


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.

0026106: BRepMesh - revision of data model

Removed tight connections between data structures, auxiliary tools and algorithms in order to create extensible solution, easy for maintenance and improvements;
Code is separated on several functional units responsible for specific operation for the sake of simplification of debugging and readability;
Introduced new data structures enabling possibility to manipulate discrete model of particular entity (edge, wire, face) in order to perform computations locally instead of processing an entire model.

The workflow of updated component can be divided on six parts:
* Creation of model data structure: source TopoDS_Shape passed to algorithm is analyzed and exploded on faces and edges. For each topological entity corresponding reflection is created in data model. Note that underlying algorithms use data model as input and access it via common interface which allows user to create custom data model with necessary dependencies between particular entities;
* Discretize edges 3D & 2D curves: 3D curve as well as associated set of 2D curves of each model edge is discretized in order to create coherent skeleton used as a base in faces meshing process. In case if some edge of source shape already contains polygonal data which suites specified parameters, it is extracted from shape and stored to the model as is. Each edge is processed separately, adjacency is not taken into account;
* Heal discrete model: source TopoDS_Shape can contain problems, such as open-wire or self-intersections, introduced during design, exchange or modification of model. In addition, some problems like self-intersections can be introduced by roughly discretized edges. This stage is responsible for analysis of discrete model in order to detect and repair faced problems or refuse model’s part for further processing in case if problem cannot be solved;
* Preprocess discrete model: defines actions specific for implemented approach to be performed before meshing of faces. By default, iterates over model faces and checks consistency of existing triangulations. Cleans topological faces and its adjacent edges from polygonal data in case of inconsistency or marks face of discrete model as not required for computation;
* Discretize faces: represents core part performing mesh generation for particular face based on 2D discrete data related to processing face. Caches polygonal data associated with face’s edges in data model for further processing and stores generated mesh to TopoDS_Face;
* Postprocess discrete model: defines actions specific for implemented approach to be performed after meshing of faces. By default, stores polygonal data obtained on previous stage to TopoDS_Edge objects of source model.
