CI: Optimize original glyph svgs [why] Often the SVGs are rather detailed and result in a big original-source.otf, which then again results in bigger than needed patched fonts. [how] Typically people suggest using svgo to make SVGs smaller, but that just tackles the representation of the icon, i.e. the actual svg file. That does not help us at all. We do not need small svg files, we need simple icons with few points and lines. svgo does not have that capability. Instead Inkscape's 'Simplify' is used. Repeated use can destroy a glyph, so we need a scale down margin to stop 'over-simplification'. The values given for the margin at the moment are purely empirical, the current glyphs survive repeated use of the new simplification script and still look good. The resultant original-source.otf file size is approximately similar to the previously achieved by Ryan's manual work. [note] We need a newer Inkscape, thus update to Ubuntu 22.04 Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
