Added image formats Image_Format_RGF_half/Image_Format_RGBAF_half
with manual conversion between 32-bit float and 16-bit half-float values.
PBR LUT table is now converted into GL_HALF_FLOAT_OES data format in case of OpenGL ES 2.0.
Graphic3d_TextureRoot::convertToCompatible() - fixed handling of
Image_Format_BGR and Image_Format_BGRA formats.

error messages have been extended by resource id.
OpenGl_Texture::InitCubeMap() now does not release cubemap
on mipmaps generation failure.
Image_PixMap::ImageFormatToString() - added method returning name of pixel format.
RWGltf_CafWriter::ToEmbedTexturesInGlb() - added option embedding textures
into GLB file enabled by default.

Default implementation detects DDS image files using Image_DDSParser parser.
Graphic3d_TextureRoot::GetImage() has been extended with new parameter
- the list of image formats supported by OpenGL driver.
Graphic3d_TextureRoot::convertToCompatible() implicitly converts
BGRA image to RGBA on OpenGL ES, which normally does not support BGR formats.
OpenGl_Caps::isTopDownTextureUV - new property defines how application defines
UV texture coordinates in primitive arrays.
OpenGl_Context::SetTextureMatrix() compares this flag with OpenGl_Texture::IsTopDown()
and automatically flips V coordinate in case of mismatch.
OpenGl_Texture now holds exact number of mipmap levels
instead of Boolean flag indicating that they are defined.
This allows loading DDS files with incomplete mipmap level set
by setting GL_TEXTURE_MAX_LEVEL to appropriate value instead of default 1000
(causing black textures in case if mipmap levels are not defined till 1x1).
Fixed order of texture coordinates transformation within GLSL program to match FFP matrix:
Rotate -> Translate -> Scale (previously Rotation was applied afterwards).
- Provide DumpJson for geometrical, ocaf and visualization classes;
- Change depth parameter of DumpJson (constant is not obligate here)
- Introduce a new macro for transient objects to be called as the first row in DumpJson: OCCT_DUMP_TRANSIENT_CLASS_BEGIN. We need not put the class name in the macro, using get_type_name of Standard_Transient for it.
- change implementation of OCCT_DUMP_CLASS_BEGIN and OCCT_DUMP_TRANSIENT_CLASS_BEGIN. It is not an sentry more and it does not create a new hierarchy level. It appends a new row into the output stream: "className": <className>
- OCCT_DUMP_* does not require semicolon
- class header is included first in source files of TDataStd, TDocStd, TCAFDoc
Build tools are updated to support building with Visual Studion 2019 toolset ClangCL (LLVM clang-cl):
- In CMake builds, use of unsupported option "-std=c++0x" is avoided
- Tool genconf recognizes availability of ClangCL toolset and proposes it in the list
- Tool genproj recognizes new compiler specification VCVER=vclang and generates VS 2019 projects for it
Note that vclang configuration puts binaries to folder "vc14" as it is compatible with vc14 CRT.
Code is updated to build with Clang for Windows without errors and warnings:
- In BVH classes, pure virtual destructors are replaced by empty ones, to avoid bogus compiler warning
- In .lex files, pragmas are added to disable warnings in parser code
- In OSD, signature of function _osd_wnt_set_error() is corrected to avoid warning on incorrect use of va_args (undefined behavior)
- In OSD_Host, OSD_Parallel_TBB, warnings on usage of deprecated function are disabled
- In Quantity_ColorRGBA and ViewerTest_CmdParser, incorrect use of predefined macro __FUNCTION__ assuming it was a string literal is avoided
- In Standard_Macro.hxx, code is reordered to handle Clang for Windows appropriately
- In AdvApp2Var_SysBase.hxx, inclusion of obsolete (MSVC-specific) header file is replaced by Standard_TypeDef.hxx
- In Standard_ErrorHandler.hxx, empty statements added to avoid warning on unused class fields
- In IVtkDraw and ViewerTest, interface is corrected to use actual type avoiding unnecessary type casts
Off-topic: corrections of some errors (uninitialized class fields) reported by VS Code Analysis in TKernel

ICC-specific preprocessor directives are added to avoid warnings.
Unused local functions and variables, class methods, unreachable statements, and extra throw() declarations reported by ICC are removed.
Usage of "expl" for name of local variable is avoided as it conflicts with standard C function "expl" defined in math.h as preprocessor macro.
Non-standard (MS-specific) argument envp is removed in definition of main() function on Windows.
Functions _main_ and _WinMain_ are renamed to Draw_Main and Draw_WinMain, respectively, to avoid using names reserved in C++.

enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.

on Windows for consistency.

(to suppress gcc/clang compiler warnings).
For MSVC compiler (version 12 and above), Handle_Class types are defined as true classes (inheriting corresponding opencascade::handle<Class>) to allow using them in "public" statement of C++/CLI language, to make these classes recognizable by other C++/CLI libraries.
Code to test operations with Handle_ class is added to QAHandleOps test command
Useless semicolons are removed after closing braces of namespaces and macros in code dependent on FreeImage and VTK.
Comments added at the closing braces of namespaces to help comprehension.
