Added missing NULL and empty result checks.
Updated test cases using offset_wire_092.brep shape containing all Edges
with TopAbs_INTERNAL orientation (hense no boundary to make offset).
Adaptations for compiling with GCC 4.7 and 4.8:
- Construction semantics is used for Handle objects being initialized by const Handle objects of derived type, to avoid overload resolution error in GCC 4.7.
- Missing includes added.
- Fixed bugs related to misuse of direct casts of handle.
- Eliminate CLang warnings on uninitialized and unused variables, functions, and expressions
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
Missing headers added; includes of headers "Handle_...hxx" removed.
Misuses of macro Handle() and its use in typedefs corrected.
Alias classes Profile and Option are removed from IFSelect; ones defined in MoniTool are used directly.
Removed header files defining only Handle classes (except Image_PixMap_Handle.hxx)
Classes SelectMgr_BaseFrustum and now inherit Standard_Transient and can be manipulated by Handle (not NCollection_Handle)
Fixed reference-type local variable pointing to temporary object
Use of handle in conditional expressions and comparisons to NULL are replaced by call to method IsNull()
1) Generic class "Intf_InterferencePolyhedron" from "Intf" package converted to the non-generic class and moved to the "IntPatch" package. Name of this class was changed to "IntPatch_InterferencePolyhedron".
2) Generic class "MoniTool_Elem" from "MoniTool" package converted to the non-generic class "MoniTool_TransientElem".
3) Generic class "IntWalk_PWalking" from "IntWalk" package converted to the non-generic class. And internal class "TheInt2S" of "IntWalk_PWalking" moved from IntWalk_PWalking.cdl to IntWalk.cdl for correct building. Also several "*.cxx" files of this class merged to one ".cxx".
4) Generic class "Transfer_SimpleBinder" from "Transfer" package converted to the non-generic class and moved to the "TransferBRep" package. Name of this class was changed to "TransferBRep_BinderOfShape".
5) Generic class "Geom2dInt_CurveTool" from "Geom2dInt" package converted to the non-generic class "Geom2dInt_Geom2dCurveTool".
6) Generic class "MAT2d_BisectingLocus" from "MAT2d" package converted to the non-generic class and moved to the "BRepMAT2d" package. Name of this class was changed to "BRepMAT2d_BisectingLocus".
7) Generic class "MAT_Mat" from "MAT" package converted to the non-generic class and moved to the "MAT2d" package. Name of this class was changed to "MAT2d_Mat2d".
