Copy constructor and assignment operator from handle of derived type is added in handle class.
They are enabled only if macro OCC_HANDLE_NOCASTS is defined, and operators of cast of handle to reference to handle to base type are disabled in that case.
Useless type casts to handle to base type are removed in GC and GCE2d classes.
Code returning reference to handle from function is corrected to return it either by value or as reference to handle of actual type.
Redundant methods Delete() and Desroy(), created in CDL as a hack to define destructor for the class, are removed; their definitions are converted to definition of destructors. In a couple of places methods Destroy() are preserved (bug made non-virtual) because they are called explicitly.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
