[Paraview] exporting selection labels to an SVG as editable/movable text-objects

[David Lonie]

Hi Roman,

Aha, the cube axis actors are still using vtkVectorText to render the text.
vtkVectorText is a text source that produces polydata to forms the
characters of the text string, and the actual text information is lost by
the time the SVG exporter processes the actors.

There was an effort in VTK to convert the cube axes to use vtkTextActor3D,
which would allow proper text exporting, but this is disabled in ParaView,
and I believe it is only experimental at this point. So unfortunately, this
is the best it gets for that particular text source at the moment.

Sorry for the misinformation earlier -- I thought you were referring to a
ParaView text source, which should export as editable text.

Dave
