including system icons in help docs

[Michael Gratton <mike vee net>]

Hi all,

Is it possible to include system icons in Yelp docs without shipping a 
copy of them?

Per[0], Geary's help manual needs to refer to accessing a secondary 
menu button, but that doesn't have a text label in the UI, just the 
standard icon (i.e. currently `︙`). So it would be better to show the 
icon in the docs instead/as well. I could just ship the Adwaita icon 
SVG, but the icon actually used in the UI like will change depending on 
the current configured desktop icon theme, so it would be better to use 
the icon loaded from the system.

I don't suppose there is a system-icon URI scheme that I could use for 
the icon's source, is there? If so, would that also work if the docs 
end up being published to the GNOME docs site?

Cheers,
//Mike
