Generation of header files from resource files was added to CMake and genproj procedures. Message_MsgFile has been extended with new method ::LoadFromString() for loading messages from embedded resources. Message_MsgFile::LoadFromString() is now a preferred way for loading message resources by application as alternative to environment variables. TObje/TObj.msg is now embedded into TObj_Application.cxx. TObj_Application now loads its global messages on instantiation of the first class instance. UnitsAPI/Lexi_Expr.dat now completely embedded into Units_Lexicon.cxx. UnitsAPI/Units.dat now embedded into Units_UnitsDictionary.cxx but can be regenerated from resource file. The definition of the following units have been removed: benne à charbon, calorie (diététique). Unused message files XSMessage/IGES.us and IGES.fr have been removed. Related code IGESData.cxx has been removed as well. XSMessage/XSTEP.us is now embedded into Interface_StaticStandards.cxx and used for fallback initialization in case when file resources defined by CSF_XSMessage environment variable are missing. SHMessage/SHAPE.us is now embedded into ShapeExtend.cxx and used for fallback initialization in case when file resources defined by CSF_XHMessage environment variable are missing. Duplicating code has been removed from ShapeProcess_OperLibrary.cxx. Shaders/Declarations.glsl and Shaders/DeclarationsImpl.glsl are now embedded into OpenGl_ShaderProgram.cxx. CSF_ShadersDirectory is no more required for using OCCT 3D Viewer. Ray-Tracing GLSL programs from Shaders are now embedded into OpenGl_View_Raytrace.cxx. File resources are still used instead of embedded programs when CSF_ShadersDirectory is defined, but this functionality is intended for OCCT development. Enumeration Graphic3d_ShaderProgram::ShaderName_Phong demonstrating custom GLSL program usage has been removed.
