Various programs and SVG image mis-rendering

[Stephen Satchell]

Who are the correct people to report issues with the incorrect display 
of SVG images?  I've encountered the problem with:

* Document Viewer
* LibreOffice Write, Calc, Impress, Draw
* GIMP

The different programs screw up in different ways.  LibreOffice Write 
can't handle an SVG image with scrunched type.  Calc, Impress, and Draw 
bungle lines with arrows.

Gimp almost gets it right; like Calc/Impress/Draw, it bungles arrows.

Chrome only messes up with color on arrows.

Firefox?  Gets it right.  Surprise.

The SVG image was created in InkScape 1.3.2 on Ubuntu 20.04.6 LTS (Focal 
Fossa). if anyone wants the .svg file in question, just ask.
