Add support for additional PlantUML options in Markdown
The AsciiDoc and RST renderers both are able to support the additional attributes that PlantUML supports (like
width), however when using Markdown these options can not be provided at all according to the documentation.
I would like to see this implemented since the usage of Markdown allows writing down UML diagrams along with formatted text with an easy syntax, plus when using SVGs, features like embedded links in graphics can be used.
I was not sure if there is any reason for this to not be implemented, so I went ahead and implemented it myself. I'm submitting the ready to review pull request for this in a few minutes, though it's probably not a perfect solution.
#40978 (closed) seems to have been opened just recently, if that already somehow works, this and the merge request can be closed.
