-@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).

 @subsection upgrade_740_stdnamespace Standard_Stream.hxx no more has "using std::" statements
 *Standard_Stream.hxx* header, commonly included by other OCCT header files, does no more add entities from *std namespace* related to streams (like *std::cout*, *std::istream* and others) into global namespace.
 The application code relying on this matter should be updated to either specify std namespace explicitly (like std::cout) or add "using std::" statements locally.
-
-@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.

-OCCT WebGL Viewer sample {#occt_samples_webgl}
-================== 
-
-This sample demonstrates simple way of using OCCT libraries in Web application written in C++ and translated into WebAssembly module using Emscripten SDK (emsdk):
-https://emscripten.org/
-
-Sample consists of the Open CASCADE 3D Viewer with a button for opening a model in BREP format.
-The sample requires a WebGL 2.0 capable browser supporting WebAssembly 1.0 (Wasm).
-
-Installation and configuration:
- 1. Install Emscripten SDK and activate minimal configuration (Python, Java and CLang) following *emsdk* documentation. Activate also MinGW when building sample on Windows host.
- 2. Build (using *emsdk*) or download FreeType static library.
- 3. Configure CMake for building Open CASCADE Technology (OCCT) static libraries (BUILD_LIBRARY_TYPE="Static").
-    For this, activate *emsdk* command prompt, configure CMake for building OCCT using cross-compilation toolchain, disable *BUILD_MODULE_Draw*. 
- 4. Perform building and installation steps.
-~~~~~
-    > ${EMSDK}/fastcomp/emscripten/cmake/Modules/Platform/Emscripten.cmake
-~~~~~
- 5. Configure CMake for building this WebGL sample using *emsdk* with paths to OCCT and FreeType. Perform building and installation steps.
- 6. Copy data/occ/Ball.brep from OCCT into "samples" folder within WebGL sample installation path.
- 7. Navigate to installation folder and start web server from it; Python coming with *emsdk* can be used for this purpose:
-~~~~~
-    > python -m SimpleHTTPServer 8080
-~~~~~
- 8. Open compatible browser and enter path taking into account your web server settings:
-~~~~~
-    > http://localhost:8080/occt-webgl-sample.html
-~~~~~
