SVGParseException marker orient="auto-start-reverse" #296
Description
I'm using your library. Thank you.
The following code throws an exception.
It seems the orient="auto-start-reverse" attribute in the marker tag is causing the issue.
According to the following, “auto” and “auto-start-reverse” are valid values:
https://developer.mozilla.org/en-US/docs/Web/SVG/Reference/Attribute/orient
I noticed this and wanted to let you know.
Thank you.
