Sequence label not displayed properly when the 'organism' type is included
This bug happens only when the image is drawn in PNG and when the sequence label position is set to middle or left. It also happens when a SVG image is inserted in a LibreOffice document.
The technical reason is because the 'organism' label is automatically put in italic using a 'tspan' tag, which doesn't work well with text anchoring during svg to png conversion using the python module cairosvg: https://github.com/Kozea/CairoSVG/issues/317.
It cannot be fixed by the GenoFig team directly.
We can temporarily remove the automatic italic style of organism labels if it really bothers people.
