Handling of special case found on some STEP files produced by FPX Expert 2013 (PCB design system):
edge curve is line displaced from its true position but with correct direction;
we shift the line in this case so that it passes through vertices correcty.
Protection against possible exception in writing XDE.
ProjCurve3d and BRepAlgo_FaceRestrictor::Perform functions should not continue to work and should terminate if the BRep_Tool::Curve function returns null pointer.
Added a transfer for ShapeRepresentationRelationship in Transfer of MappedItem method,
in order to support link of components according to ISO 10303-203-2003.
Datum reading changed in ReadDatums() method:
using DatumSystemAP242 (DatumSystem or DatumReference) array
instead of DatumSystem array (DatumReference)
The new transform persistence mode, with flag `Graphic3d_TMF_OrthoPers`, can be combined (bitwise OR operation) with the other persistence modes (2D, Trihedron or Zoom/Rotate Persistence) to make objects be rendered with orthographic projection when it is on a view with perspective projection.
If the view already uses orthographic projection, there will be no difference.
This feature was implemented to fix ViewCube being distorted when view with perspective projection changes size.

Changed myHasEntityWithPersistence to a counter.
Renamed variable to myNbEntityWithPersistence.
Modified HasEntityWithPersistence() method.
Modified logical test in SelectMgr_ViewerSelector::traverseObject.
Added AIS_DragAction_Confirmed drag action, which will be called by AIS_ViewController when the drag interaction is confirmed (mouse moved more than click threshold).
Integrated DE plugin functionality.
Reworked DE components:
- TKDESTEP: Handling STEP file format.
- TKDEOBJ: Handling OBJ file format.
- TKDEIGES: Handling IGES file format.
- TKDEGLTF: Handling GLTF file format.
- TKDEVRML: Handling VRML file format.
- TKDEPLY: Handling PLY file format.
- TKDESTL: Handling STL file format.
Reworked DE DRAW components:
TKXSDRAWSTEP: Container for DE command to work with STEP.
TKXSDRAWOBJ: Container for DE command to work with OBJ.
TKXSDRAWIGES: Container for DE command to work with IGES.
TKXSDRAWGLTF: Container for DE command to work with GLTF.
TKXSDRAWVRML: Container for DE command to work with VRML.
TKXSDRAWPLY: Container for DE command to work with PLY.
TKXSDRAWSTL: Container for DE command to work with STL.
TKXSDRAW rework to be base DRAW plugin to keep DE session and utils.
Updated documentation
Updated samples
NCollection containers update:
- NCollection_Array1 - updated functionality
- NCollection_Array2 - NCollection_Array1 as a wrapper for 2array
- NCollection_Vector -> NCollection_DynamicArray was renamed and reworked.
TCollection:
- Use static empty string to avoid allocations on empty string
NCollection allocators update:
- NCollection_Allocator - allocator that used Standard::Allocate
- NCollection_OccAllocator - allocator-wrapper that used OCC BaseAllocator objects
- NCollection_IncAllocator - rework to increase performance
Standard:
- Rework functionality to use different allocation libs
- Implement basic of new way to wrap allocations tools
- Define 4 ways to allocation (defines in configure stage)
Additional changes:
- Hash function uses std::hash functionality
- size_t as a hash value
- New HashUtils with Murmur and FVN hash algo for x32 and x64
- Deprecated _0.cxx and .gxx DE classes reorganized
- Create own utility for std memory
- Update Standard_Transient to be more platform-independent
Math TK changes:
- math_Vector -> match_BaseVector<>
- Buffer decreased to cash 32 elements instead of 512
Reading and writing of triangle_strips and triangle_fans has been corrected in RWStepVisual_RWComplexTriangulatedFace.cxx file. And corresponding corrections have been added to other files.
Added support of reading and writing of the triangulated_surface_set.
Prevented creation of tesselated geometry under the schemas different from AP242DIS.
test step_read corrected, switched parameter write.step.schema to AP242DIS in begin and back to AP214CD at the end
Selecting the middle point between XInf and XSup leads situation, where X values almost does not change.
To prevent this situation, select shifted point instead of middle.
Changed iteration limits from theTriangulation->NbTriangles() to theTriangulation->NbNodes()
Provided modification of the normals only with rotation (gp_GTrsf::Form() == gp_Other leads to crash)
Added condition to not remove face image, consisting only of invalid edges for artifactically invalid face.
This face image should be connected with other image faces minimum through the edge.
Pass pointer to DEXCAFCascade_ConfigurationNode to DEXCAFCascade_Provider;
Remove forcible manual reset of Provider's node in DE_Wrapper::FindProvider() to verify that all specializations of configuration node work properly without necessity of workarounds.
