[vtkusers] Missing functions after building of VTK 7.1.0 with Java-wrapper

[David Gobbi]

All those methods are present in the Tcl and Python wrappers, only the Java
wrappers seem to be missing them.

I have an idea about why the methods are missing, and I think it has to do
with the rearrangement of the public and private dependencies in the
module.cmake files that occurred a few months ago (commit 6e113ad4).

For "vtkParametricSpline *vtkSplineWidget::GetParametricSpline()", the
vtkParametricSpline class is in vtkCommonComputationalGeometry, which is in
the PRIVATE_DEPENDS section of the module.cmake for vtkInteractionWidgets
(the module that vtkSplineWidget is inside of).

In C++, this private dependency works fine because the forward declaration
of vtkParametricSpline in vtkSplineWidget.h is sufficient.  All C++ needs
to know is that the vtkParametricSpline class has a definition somewhere,
but it doesn't actually need the definition.  Not so for Java.
Unfortunately, Java needs the definition of vtkParametricSpline in order to
wrap the vtkSplineWidget.GetParametricSpline() method.  For the wrappers,
it would usually get the definition through a complicated mechanism
involving the vtkInteractionWidgetsHierarchy.txt that the wrappers build,
but the Hierarchy.txt files are built according to the DEPENDS section of
the module.cmake files and they ignore the PRIVATE_DEPENDS section.

So a potential solution is use both the DEPENDS and PRIVATE_DEPENDS when
building the Hierarchy.txt files for the wrappers.  This is something that
I can look into.
