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

[Dr. Roman Grothausmann]

Dear Dave,


Many thanks for fixing the Label exporter issue. It does work with 4.1 to get 
the text exported into e.g. an SVG. However, the text is always rendered as 
paths (always consists of triangles). Is it also possible to have the text being 
exported as actual text-fields (like e.g. gnuplot does) that can be edited with 
the text-tool in e.g. inkscape?
This would be especially helpful when rendering axes of objects, exporting these 
as SVGs and then letting latex render the text when the SVGs are included in an 
article (as described here: http://www.ctan.org/tex-archive/info/svg-inkscape).

Many thanks again for looking into this
Roman
