Exporting selection labels as text ("Render text as paths" not checked) works 
for me with PV-4.1.0. However, PV-4.1.0 does not allow one to specify the 
formatting, like printf formats as: %.2f\circ.
PV-4.3.1 does allow one to specify the formatting, however whether "Render text 
as paths" is checked or not, the output SVG does not contain any text-tags any 
more, that would allow editing in inkscape or text setting by latex.

Did Your changes get lost/reverted?

I tried to find the commits that made it possible for PV-4.1 but could not find 
them in the git logs:
http://www.paraview.org/gitweb?p=ParaView.git&a=search&h=HEAD&st=commit&s=gl2ps
It seems the bug number 14231 was never mentioned in the commit messages.

What is the general procedure to find the right commits in such a case?

Many thanks for looking into this.
Roman
