0028840: Data Exchange - rewrite the STL Reader/Writer
STL Reader and Writer tools have been refactored to improve performance and usability:
- Basic reading of STL file is separated to abstract class RWStl_Reader which is not bound to particular data structures; the target data model can be bound via inheritance.
- RWStl package uses class Poly_Triangulation to represent triangular mesh.
- Obsolete data structures and tools (packages StlMesh and StlTransfer) are removed.

Template for LaTeX header used in generation of PDF manuals is corrected to avoid multiple errors during processing by LaTeX (which can eventually lead to LaTeX aborting if their count exceeds 100).
Names of log files generated by gendoc command are made dependent on target format and (for PDF output) document name.
0028912: Visualization, TKOpenGl - multi-texture support
Graphic3d_AspectFillArea3d now stores array of textures.
Graphic3d_TextureParams stores texture unit for mapping texture.
OpenGl_Context::BindTextures() - context now manages the set of active textures.
Related code has been removed from OpenGl_Workspace.

OpenGl_Texture now holds OpenGl_Sampler instance as class field.
OpenGl_Texture inherits new class OpenGl_NamedResource and holds
texture identifier used for sharing resource in OpenGl_Context.
OpenGl_RaytraceGeometry now creates bindless textures taking
Sampler object directly from OpenGl_Texture.
OpenGl_Context::BindTextures() automatically recreates immutable

Added support of Visual Studio 2017 (15) in CMake build procedure.
CMake 3.7.2 or above is required to generate projects for VS 2017.
Since version of compiler and toolset remained at 14 (now they are 14.1), and they use the same run-time, the same third-party products as for VS 2015 (14) can be used.
Also the name of the folder for installation of OCCT binaries in OCCT-standard layout (default on Windows) remains "vc14".
Support of Visual Studio 2017 is added in genproj generator and relevant environment, with format specifier "vc141".
The syntax of the genproj command is revised:
- UWP is considered as separate platform ("uwp" alternative to "wnt"), not part of IDE specification
- Option "IDE" is renamed to "Format"
- Obsolete name of local variable "aWokStation" is replaced by equivalent "theFormat"
In environment scripts, additional variables are defined (derived from VCVER, see adm/vcver.bat):
- VCLIB defines name of the subdirectory specific to VS version; it is the same as VCVER except that for VCVER=vc141 VCLIB=vc14 and for VCVER=141-uwp VCLIB=vc14-uwp
- VCFMT is VCVER without optional suffix "-uwp"
- VCPROP is "NativeDesktop" for normal builds or "Universal" for UWP builds
Command genconf is amended to:
- Detect presence of VS 2017 (separately for desktop and UWP)
- Use only two first digits after "vc" in format specification for search of third-party libs
- Have more space in user interface for VS specification
All supported variants of VCVER variable are documented in dev guides / buiding / msvc
0028890: Visualization - After closing all views and then display the view again, just the first view has object(s) displayed

1. Refactoring of the Error/Warning reporting system of the algorithms in Boolean Component.
To dump the description of the Error/Warning status of the algorithm the DumpErrors/DumpWarnings method should be called.
Also, the methods GerErrorMsg(int Error) and GetWarningMsg(int Warning) have been implemented to get the description for the given Error/Warning.
All Error/Warning statuses are now listed in the enumeration ErrorStatusEnum/WarningStatusEnum of the algorithm.
It is also possible to get the shapes for which the warning has been set by using the method GetWarningShapes().
2. The new class BOPAlgo_Options has been created to unify the options of the BOPAlgo_* and BRepAlgoAPI* algorithms.
3. The new checks across the algorithms have been added to detect and report errors and warnings.
4. Test cases
boolean bopcut_complex B9 E1 E5 E8
boolean bopfuse_complex B4 B5 C9 D1 D4 D5 D6 D7

0028417: Using PRECOMPILED HEADER to speed up compilation time
Use of Cotire tool is introduced for acceleration of CMake builds, by usage of precompiled headers.
CMake option BUILD_USE_PCH is added to enable / disable use of precompiled headers
When precompiled headers are used, additional compiler macros are defined globally in the build system to avoid problems due to different order of included files:
- NOMINMAX is defined on Windows to prevent defining "min" and "max" as macros by windows.h
- STRSAFE_NO_DEPRECATE and _SCL_SECURE_NO_WARNINGS are defined on Windows to prevent declaring functions of standard C library as deprecated by #pragma, and other warnings in system headers
- GL_GLEXT_LEGACY and GLX_GLEXT_LEGACY are defined to ensure that only OCCT's own glext.h is used
- __STDC_FORMAT_MACROS is defined to have standard C print format macros always defined
Code is corrected to avoid conflicts with system headers and in case of compiling together as unity builds (partially):
- Some locally defined variables in TKV3d, TKHLR are renamed to be unique
- Duplicated definitions of macros and global functions are eliminated in TKSTEP
- Useless header WNT_UInt.hxx is removed
- Usage of local variables conflicting with X11 macro is avoided in Draw_Viewer.cxx
- Local variables in AIS_ConcentricRelation.cxx are renamed to avoid conflict with macros defined in windows.h
- HXX files containing code are renamed to PXX or merged with corresponding CXX files.
IVtkTools classes are corrected to avoid compiler warnings disabled in non-PCH builds by inclusion of VTK headers.
Useless pragmas disabling warnings on MSVC are removed
0028710: Implement 'BRepTools_History' history for algorithm 'ShapeUpgrade_UnifySameDomain'
'BRepTools_History' history was implemented for algorithm
'ShapeUpgrade_UnifySameDomain'.
The history of the changing of the initial shape was corrected to consider all
shapes created by the algorithm as modified shapes instead of generated ones.
The old history interface was replaced by the new one:

3. Method ShapeConstruct_ProjectCurveOnSurface::ApproxPCurve is modified to avoid regressions: now it takes care of the set of initial points to be enough close to each other so that an interval between two adjacent points is less than half-period of the surface.

0028708: Create a mechanism to serve shape history by a way common for algorithms accepting and producing shapes
A shape history mechanism was created. It supports history for shapes with types
'vertex', 'edge', 'face' and 'solid'. It allows define relations 'generated',
'modified' and 'removed' between the accepted and the produced shapes. It
provides functionality for the other widely used history mechanism 'Generated',
'Modified', 'IsDeleted'. It provides algorithm to merge two histories of
sequentially applied algorithms. Recommendations were formalized to choose
