bf5f0ca20a 0029570: Visualization, Graphic3d_Aspect - merge Graphic3d_Group aspects
Graphic3d_AspectFillArea3d, Graphic3d_AspectLine3d, Graphic3d_AspectMarker3d
and Graphic3d_AspectText3d have been merged into new class Graphic3d_Aspects.
The old classes are preserved as dummy sub-classes of Graphic3d_Aspects
preserving different per-aspect defaults.

Methods IsGroupPrimitivesAspectSet(), GroupPrimitivesAspect(), FillAreaAspect(),
LineAspect() and MarkerAspect() have been removed from Graphic3d_Group.
Instead, a new method Graphic3d_Group::ReplaceAspects() has been introduced
for replacing existing group aspects.

AIS_Shape now uses new method AIS_InteractiveObject::replaceAspects()
for updating computed groups with new aspects without presentation recomputation
in places where SynchronizeAspects() is not applicable.

OpenGl_AspectFace, OpenGl_AspectLine, OpenGl_AspectMarker
and OpenGl_AspectText have been merged into new class OpenGl_Aspects.

ViewerTest::parseColor() - fix uninitialized alpha component.
Graphic3d_AspectText3d/Prs3d_TextAspect - removed unused properties Space, ExpansionFactor, Angle.
Remove getters Values() deprecated since OCCT 7.1.0.

7bd071edb1 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.

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.

778cd66786 0027860: Visualization - clean up Transformation Persistence API
Graphic3d_Camera::TransformMatrices redundant NCollection_Handle usage
has been replaced with validity flags.

Graphic3d_TransModeFlags now defined as enumeration, not integer bit flags.
Graphic3d_TMF_PanPers and Graphic3d_TMF_FullPers have been removed.
Graphic3d_TMF_ZoomRotatePers has been introduced.

Graphic3d_TransformPers is now inherits Standard_Transient.
Graphic3d_TransformPers now defines dedicated constructors
for 3D persistence (zoom / rotate) and 2D persistence (2d / trihedron).
2D persistence now supports dedicated values for X and Y offsets.
The corner is now specified by enumeration Aspect_TypeOfTriedronPosition
instead of indirect interpretation of anchor point values.
Fixed handling of Graphic3d_TMF_ZoomRotatePers (combination of Graphic3d_TMF_RotatePers + Graphic3d_TMF_ZoomPers).

PrsMgr_PresentableObject, Graphic3d_CStructure now hold
Handle(Graphic3d_TransformPers) instead of a value.
Method ::SetTransformPersistence(), ::TransformPersistence()
now works with Handle(Graphic3d_TransformPers).
Old methods have been marked deprecated.

b647266461 0027670: Visualization - avoid duplication of structures defining primitive array presentation aspects
Quantity_ColorRGBA has been introduced as convenient structure holding Vec4 for OpenGL.
Graphic3d_PolygonOffset has been added as replacement for TEL_POFFSET_PARAM.

Duplicating definition of Hatch Styles TEL_HS_*** has been removed;
Aspect_HatchStyle enum now follows values of TEL_HS_*** for compatibility.
TelCullMode enum has been removed.

Aspect_AspectLine has been merged into Graphic3d_AspectLine3d.
Aspect_AspectMarker has been merged into Graphic3d_AspectMarker3d.
Aspect_AspectFillArea has been merged into Graphic3d_AspectFillArea3d.

OpenGl_AspectText now stores Graphic3d_AspectText3d as class field.
OpenGl_AspectFace now stores Graphic3d_AspectFillArea3d as class field.

Graphic3d_AspectFillArea3d - back face culling is now enabled by default.
TKOpenGl now relies on Graphic3d_Group::IsClosed() flag to disable face culling.

CALL_DEF_MATERIAL, CALL_DEF_TRANSFORM_PERSISTENCE, TEL_POINT, TEL_COLOUR
have been removed.

OpenGl_Workspace::myAspectFaceApplied and myAspectMarkerApplied have been replaced
from OpenGl_AspectFace*/OpenGl_AspectMarker*
to Handle(Graphic3d_AspectFillArea3d)/Handle(Graphic3d_AspectMarker3d).
This eliminates reading from freed memory
(e.g. when OpenGl_AspectFace is allocated on stack like in OpenGl_Trihedron).

OpenGl_PrimitiveArray::drawEdges() - fix drawing non-indexed array from VBO (access violation due to NULL handle).
