e2d60d0f7f 0029325: Modeling Algorithms - add tool BRepLib_PointCloudShape for generation point cloud for specified shape
Added PLY writing tools RWPly_CafWriter and RWPly_PlyWriterContext.

Added tool BRepLib_PointCloudShape generating point cloud from shape in two ways:
- random points on surface with specified density;
- points from triangulation nodes.

StdPrs_ToolTriangulatedShape::ComputeNormals() has been moved to
BRepLib_ToolTriangulatedShape for reusing outside of AIS.

Command vpointcloud has been extended to use new generation tool.
Command writeply has been added to write triangulation or point set into PLY format.

e816dce36e 0032086: Visualization - support deferred data loading
1) Extend Poly_Triangulation by mesh purpose, possibility to be cleared and late-load deferred data interfaces.
2) Update BRep_TFace to store list of triangulations istead of single one. And also active one. Update getter and setter of single triangulation and add new methods to interaction with whole triangulations list.
3) Update BRep_Tool to get single triangulation of face according to the input mesh purpose or whole triangulations list.
4) Update BRep_Builder to make face by not only single triangulation but whole triangulations list with specified active one.
5) Add new methods to BRepTools to interact with shape triangulations (Load/Unload/Activate/LoadAll/UnloadAllTriangulation(s))
6) Add new 'tlateload'command for shape to load/unload/activate triangulations.
7) Update 'trinfo' command by '-lods' options to print detailaed information about LODs of this shape
8) Support empty triangulations by selection. Use bounding box selection in this case.
9) Add new 'outdisplist' option to XDispaly command to print list of displayed objects to output variable but not to theDI
10) Add new '-noecho' option to vdisplay command to skip printing of displayed objects to theDI
11) Create new RWMesh_TriangulationSource as mesh data wrapper for delayed triangulation loading.
12) Create new RWMesh_TriangulationReader as base interface for reading primitive array from the buffer.
13) Cache nodes/triangles number defined in glTF file
14) Use RWMesh_TriangulationSource class as base of RWGltf_GltfLatePrimitiveArray one and RWMesh_TriangulationReader class as base of RWGltf_TriangulationReader one
15) Add possibilty to support of LODs by glTF reader. It is possible to skip data loading and load them later
16) Add new '-skiplateloading' (to skip triangulation loading), '-keeplate' (to keep information about deferred storage to load/unload triangulation later),
'-toprintdebuginfo' (to print additional debug information) options to ReadGltf command
17) Add new test of glTF late loading
