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()
