Summary0022834: Instable case testing 3d offset algorithm (problem with cone-like surfaces)
DescriptionThe case is

chl 937 A6

There are some BSpline surfaces that look like cones in initial shape, 3d offset fails. The problem is in usage of Geom_OsculatingSurface.
Additional information
and documentation updates		Modified entities:

Geom_OsculatingSurface.cxx

modified methods:

Standard_Boolean Geom_OsculatingSurface::IsQPunctual
                  (const Handle(Geom_Surface)& S,
                   const Standard_Real Param,
                   const GeomAbs_IsoType IT,
                   const Standard_Real TolMin,
                   const Standard_Real TolMax) const
"TolMin" is not used now.

void Geom_OsculatingSurface::Init(const Handle(Geom_Surface)& BS,
                                  const Standard_Real Tol)
the inner initial surface "InitSurf" is now approximated if its degree is too low.
TagsNo tags attached.

Dear BugMaster,
  Workbench KAS:dev:apn-22834-occt was created from SVN branch http://svn/svn/occt/branches/22834
  (and apn-22834-products from trunk) and compiled on Linux and Windows platforms.

   There are compilation errors on Linux and Windows:

I cannot reproduce unstable behavior for Windows, debug mode.
According to info of MKV, bug chl 937 A6 is now tests/bugs/modalg_4/bug8842_6.
Please test it for different platforms and modes.
Use please pure master version, without any correction made by JGV for this bug.
