-@section occt_debug_sanitizers Use of compiler sanitizers
-
-GCC and Clang compilers provide options for instrumenting the code with the tools intended for detection of run-time errors, called sanitizers.
-This section provides some hints for using sanitizers for detecting possible errors in OCCT code.
-
-@subsection occt_debug_sanitizers_linux Linux
-
-Example of configuration steps for Ubuntu:
-
-1. In CMake configuration:
-
-  - Use up-to-date version of the GCC or CLang compiler; make sure that if CMAKE_CXX_COMPILER is set to C++ compiler (e.g. "clang++-6.0") and CMAKE_C_COMPILER is set to C compiler (e.g. "clang-6.0")
-  - Ensure that CMAKE_LINKER is set to the C++ linker bundled with compiler (e.g. clang++-6.0); this is important to avoid linking problems
-  - For building with Address sanitizer, set CMAKE_CXX_FLAGS and CMAKE_C_FLAGS to "-fsanitize=address -fno-omit-frame-pointer -fno-optimize-sibling-calls"
-  - For building with Undefined Behavior sanitizer, set CMAKE_CXX_FLAGS and CMAKE_C_FLAGS to "-fsanitize=undefined -fno-omit-frame-pointer -fno-optimize-sibling-calls"
-  - Set CMAKE_BUILD_TYPE to RelWithDebInfo to get more informative stack traces on errors
-
-2. Build as usual (make)
-
-  Be prepared that it works much slower than normal build and consumes more disk space.
-
-3. Before running executable, make sure that "llvm-symbolizer" is in PATH; this is necessary to get human-readable stack traces. The tool must have exactly that name.
-
-  If it is installed in common folder (/usr/bin or similar) with different name, one option is to create a symlink, for instance:
-> sudo ln -s /usr/bin/llvm-symbolizer-6.0 /usr/bin/llvm-symbolizer
-
-  Alternatively, add directory where actual llvm-symbolizer is located (such as /usr/lib/llvm-6.0/bin) to the PATH variable. 
-
-4. Set environment variable to disable memory leaks detection (they seem to be reported for every global variable at exit, not much useful):
-> export ASAN_OPTIONS=detect_leaks=0
-
-5. Set environment variable CSF_CPULIMIT_FACTOR to reasonably large number to increase the time limits for program execution (used by OCCT tests) to compensate the performance penalty introduced by sanitizers:
-> export CSF_CPULIMIT_FACTOR=20
-
-6. When using UBSan, set environment variable UBSAN_OPTIONS to get stack traces:
-> export UBSAN_OPTIONS=print_stacktrace=1
-
-7. Run DRAW and perform tests as usual, keeping in mind that running with sanitizer is much heavier than normal build:
-> ./draw.sh relwithdeb  <br>
-> Draw[]> testgrid -parallel 0
-
-Note that when running tests under sanitizers, behavior may be different.
-Known problems (as of CLang 6.0) are:
-- Software signals (access violation etc.) are not handled
-- Heap memory usage always reports zero
-
-@subsection occt_debug_sanitizers_windows Windows
-
-Though CLang toolset is available in Visual Studio 2015 and newer, sanitizer do not seem to be available out of the box (last tested with VS 2019 16.2.3).

-@section upgrade_occt750 Upgrade to OCCT 7.5.0
-
-@subsection upgrade_750_srgb_color RGB color definition
-
-OCCT 3D Viewer has been improved to properly perform lighting using in linear RGB color space and then convert result into non-linear gamma-shifted sRGB color space before displaying on display.
-This change affects texture mapping, material definition and color definition.
-
-Previously *Quantity_Color* definition was provided with unspecified RGB color space.
-In practice, mixed color spaces have been actually used, with non-linear sRGB prevailing in general.
-Since OCCT 7.5.0, *Quantity_Color* now specifies that components are defined in linear RGB color space.
-
-This change affects following parts:
-* Standard colors defined by *Quantity_NameOfColor* enumeration have been converted into linear RGB values within Quantity_Color construction.
-* Application may use new enumeration value *Quantity_TOC_sRGB* for passing/fetching colors in sRGB color space,
-  which can be useful for interoperation with color picking widgets (returning 8-bit integer values within [0..255] range)
-  or for porting colors constants within old application code without manual conversion.
-* *Graphic3d_MaterialAspect* color components are now expected in linear RGB color space,
-  and standard OCCT materials within *Graphic3d_NameOfMaterial* enumeration have been updated accordingly.
-* Texture mapping now handles new *Graphic3d_TextureRoot::IsColorMap()* for interpreting content in linear RGB or sRGB color space.
-  It is responsibility of user specifying this flag correctly. The flag value is TRUE by default.
-* Method *Image_PixMap::PixelColor()* has been extended with a new Boolean flag for performing linearization of non-linear sRGB.
-  This flag is FALSE by default; application should consider passing TRUE instead for further handling *Quantity_Color* properly as linear RGB values.
-
-@subsection upgrade_750_aspectwindow Aspect_Window interface change
-
-Unexpected const-ness of Aspect_Window::DoResize() method has been removed, so that application classes implementing this interface should be updated accordingly.
-
-@subsection upgrade_750_rename Renaming of types
-
-Enumeration BRepOffset_Type is renamed to ChFiDS_TypeOfConcavity.
-
-@subsection upgrade_750_tkv3d TKV3d/TKService toolkits changes
-
-The following changes could be highlighted while porting:
-* *Prs3d::GetDeflection()* has been moved to *StdPrs_ToolTriangulatedShape::GetDeflection()*.
-* *Prs3d_ShapeTool* has been moved to *StdPrs_ShapeTool*.
-* *StdSelect_ViewerSelector3d* has been moved to *SelectMgr_ViewerSelector3d*.
-* *Font_BRepFont* has been moved to *StdPrs_BRepFont*.
-* Visualization classes now use *TopLoc_Datum3D* (from *TKMath*) instead of *Geom_Transformation* (from *TKG3d*) as smart pointer to *gp_Trsf*.
-  This is rather an internal change, but some applications might need to be updated.
-
-@subsection upgrade_750_hlrangle Prs3d_Drawer deviation angle
-
-Properties Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::HLRDeviationCoefficient() have been removed from classes *Prs3d_Drawer*, *AIS_Shape* and *AIS_InteractiveContext*.
-Prs3d_Drawer::DeviationAngle() should be now used instead of Prs3d_Drawer::HLRAngle() and Prs3d_Drawer::DeviationCoefficient() instead of Prs3d_Drawer::HLRDeviationCoefficient().
-The default value of Prs3d_Drawer::DeviationAngle() property has been changed from 12 to 20 degrees to match removed Prs3d_Drawer::HLRAngle(), previously used as input for triangulation algorithm.
-
-@subsection upgrade_750_hlrprs Changes in HLR presentation API
-
-Methods computing HLR presentation within *PrsMgr_PresentableObject::Compute()* have been renamed to *PrsMgr_PresentableObject::computeHLR()*
-and now accept *Graphic3d_Camera* object instead of removed *Prs3d_Projector*.
-
-@subsection upgrade_750_dimensions Dimension and Relation presentations moved from AIS to PrsDim
-
-Presentation classes displaying Dimensions and Relations have been moved from *AIS* package to *PrsDim*.
-Corresponding classes should be renamed in application code (like *AIS_LengthDimension* -> *PrsDim_LengthDimension*).
-
-@subsection upgrade_750_sensitiveEntity Select3D_SensitiveEntity interface change
-
-The method Select3D_SensitiveEntity::NbSubElements() has been changed to be constant. Select3D_SensitiveEntity subclasses at application level should be updated accordingly.
-
-
-@subsection upgrade_750_Booleans Changes in Boolean operations algorithm
-
-* TreatCompound method has been moved from *BOPAlgo_Tools* to *BOPTools_AlgoTools*. Additionally, the map parameter became optional:
-~~~~
-void BOPTools_AlgoTools::TreatCompound (const TopoDS_Shape& theS,
-                                        TopTools_ListOfShape& theLS,
-                                        TopTools_MapOfShape* theMap = NULL);
-~~~~
-
-@subsection upgrade_750_Adaptor2d_OffsetCurve  Offset direction change
-
-Offset direction, which used in class Adaptor2d_OffsetCurve for evaluating values and derivatives of offset curve is unified for offset direction used in class Geom2d_OffsetCurve: now offset direction points to outer ("right") side of base curve instead of the previously used inner ("left") side. Old usage of class in any application should be changed something like that:
-
-Adaptor2d_OffsetCurve aOC(BaseCurve, Offset) --> Adaptor2d_OffsetCurve aOC(BaseCurve, -Offset)
-
-@subsection upgrade_750_message_messenger Message_Messenger interface change
-
-Operators << with left argument *Handle(Message_Messenger)*, used to output messages with
-a stream-like interface,  have been removed.
-This functionality is provided now by separate class *Message_Messenger::StreamBuffer*.
-That class contains a stringstream buffer which can be filled using standard stream
-operators. The string is sent to a messenger on destruction of the buffer object,
-call of its method Flush(), or using operator << with one of ostream manipulators 
-(*std::endl, std::flush, std::ends*). Manipulator *Message_EndLine* has been removed,
-*std::endl* should be used instead.
-
-New methods *SendFail(), SendAlarm(), SendWarning(), SendInfo()*, and *SendTrace()* are
-provided in both *Message_Messenger* class and as static functions in *Message* package
-(short-cuts to default messenger), returning buffer object for the output of
-corresponding type of the message.
-
-The code that used operator << for messenger, should be ported as follows.
-
-Before the change:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  theMessenger << "Value = " << anInteger << Message_EndLine;
-~~~~~
-
-After the change, single-line variant:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  theMessenger->SendInfo() << "Value = " << anInteger << std::endl;
-~~~~~
-
-After the change, extended variant:
-~~~~~
-  Handle(Message_Messenger) theMessenger = ...;
-  Message_Messenger::StreamBuffer aSender = theMessenger->SendInfo();
-  aSender << "Array: [ ";
-  for (int i = 0; i < aNb; ++i) { aSender << anArray[i] << " "; }
-  aSender << "]" << std::endl; // aSender can be used further for other messages
-~~~~~
-
-@subsection upgrade_750_message_printer Message_Printer interface change
-
-Previously, sub-classes of *Message_Printer* have to provide a triplet of *Message_Printer::Send()* methods accepting different string representations: TCollection_AsciiString, TCollection_ExtendedString and Standard_CString.
-*Message_Printer* interface has been changed, so that sub-classes now have to implement only single method *Message_Printer::send()* accepting TCollection_AsciiString argument and having no Endl flag, which has been removed.
-Old three Message_Printer::Send() methods remain defined virtual with unused last argument and redirecting to new send() method by default.
