Excellent. This also solves the blue-notes issue in Firefox for me, even 
after clipping in Inkscape. So, to summarize for reference:

1.) For cropping,
  inkscape --verb=FitCanvasToDrawing --verb=FileSave --verb=FileClose 
file.svg
works, but has some caveats (probably for non-standard-conforming 
viewers only, including Wikipedia's SVG-to-PNG-converter).

2.a) Firefox in some version(s) draws elements with links in blue if the 
a tag does not specify another color.
2.b) Since Inkscape's FitCanvas rewrites the entire SVG and drops those 
(seemingly superfluous) color attributes, you have to use a different 
route with links: https://github.com/skagedal/svgclip
2.c) svgclip does not handle position of real text properly, hence you 
have to convert to paths first.
  inkscape --verb=EditSelectAllInAllLayers --verb=ObjectToPath 
--verb=FileSave --verb=FileClose file.svg
  ./svgclip.py -o cropped.svg file.svg
That's the only universal variant we have for SVGs with links.

3.) Even without links, "real" text causes funny positions with 
Wikipedia's PNG thumb renderer [1]. Hence,
  inkscape --verb=EditSelectAllInAllLayers --verb=ObjectToPath 
--verb=FitCanvasToDrawing --verb=FileSave --verb=FileClose file.svg
should be okay for SVGs with \pointAndClickOff, eliminating the need for 
an additional tool.


Correct?
