DCAF require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a dublicates of the
internal static singletons. This means each dynamic library
will have their own instance of the static singleton.
Update all direct library loading to use the DCAF plugin
mechanism. This will ensure that the DCAF plugin is loaded
only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen

- Fixed condition to allow proceeding of nested compounds;
- Added new key to "reshape" draw command to state a level of type until which requests are taken into account;
- Test case added.
The previous code has a condition to avoid processing the same faces if the face has a location.
The similar condition should be applied during the edges processing.
If not doing this, in the previous implementation, IMeshData_Edge instances are created for all edges(even located), but edges of faces located are not filled with curves.
As a result we had wrong local selection of edges.
Limit addition of edges to data model by ones with unique TShape and location using edges map already available in BRepMesh_ShapeVisitor.
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.
Component is now spread over IMeshData, IMeshTools, BRepMeshData and BRepMesh units.
<!break>
1. Extend "tricheck" DRAW-command in order to find degenerated triangles.
2. Class BRepMesh_FastDiscret::Parameters has been declared as deprecated.
3. NURBS range splitter: do not split intervals without necessity. Intervals are split only in case if it is impossible to compute normals directly on intervals.
4. Default value of IMeshTools_Parameters::MinSize has been changed. New value is equal to 0.1*Deflection.
5. Correction of test scripts:
1) perf mesh bug27119: requested deflection is increased from 1e-6 to 1e-5 to keep reasonable performance (but still reproducing original issue)
2) bugs mesh bug26692_1, 2: make snapshot of triangulation instead of wireframe (irrelevant)
Correction in upgrade guide.
1. New testgrid "lowalgos/intss" has been created. It will contain all test cases on geometrical intersection of two surfaces ("intersect" DRAW-command) and two faces ("bopcurves" DRAW-command).
2. New test case for the issue #28493 has been created because the problem is not reproduced on MASTER.
3. Test case (lowalgos/intss/bug24472) for the issue #29501 has been modified in order to check loops of the resulting intersection curves.
Bnd_OBB constructor from Bnd_Box is fixed for VOID input.
DRAW command bounding command is adjusted:
- Support of old syntax 'bounding shape'is restored.
- Exception on VOID bounding box is avoided.
- Arguments are handled in case-insensitive way.
- Options -s, -perfmeter, and ability to set result as first argument are removed as redundant.
- Help is moved to command definition.
Separate command OCC29311 is added (in QADraw) to do the same as option -perfmeter did; tests are updated.
The reason of this issue is in incorrectly interpreted the generic class "TheExtPC" (eliminated after the fix 0024773) as Extrema_ExtPC2d. Correct interpretation must be "Extrema_EPCOfExtPC2d" class.
Now this problem has been fixed in the class Geom2dGcc_Circ2dTanCenGeo.
New testgrid "lowalgos 2dgcc" has been created.
Test parse rules are improved to recognize messages with word 'fail' or 'failure' as errors.
Test cases are corrected accordingly (TODO or REQUIRED statements added where fail messages were not noticed previously).
