[vtkusers] Unicode support for Axis Titles and Labels in vtkCubeAxesActor2D

[David Lonie]

Unfortunately vtkCubeAxesActor2D still uses vtkVectorText internally
by default, which ignores the font family entirely. So custom font
files will not be used with it.

There is an experimental feature to use a vtkTextActor3D (which
supports custom fonts) in place of vtkVectorText that may work for
you, but I'm not sure if it's in a usable state at this point. You can
try it by getting the 3 vtkAxisActor2D instances out of the cube axes
and calling UseTextActor3DOn for them:

cubeAxes2D->GetXAxisActor2D()->SetUseTextActor3D(1);
cubeAxes2D->GetYAxisActor2D()->SetUseTextActor3D(1);
cubeAxes2D->GetZAxisActor2D()->SetUseTextActor3D(1);

It looks like the Use2DMode setting on the axis actors would use a
vtkTextActor, which supports custom fonts as well. Hopefully one of
these will work for you.

HTH,
Dave
