There have been user requests for underline (a text decoration) going back years and years. Since it has not shown up I assume this means that some library Inkscape depends on cannot do this. I checked the most obvious suspects and did not find a definitive smoking gun:
1. Freetype does support underlining (both location and thickness). http://www.cs.sunysb.edu/documentation/freetype-2.1.9/docs/tutorial/step2.ht...
2. SVG supports it with "text-decoration:underline".
3 Pango supports it: https://developer.gnome.org/pango/stable/PangoMarkupFormat.html
4. Cairo - not sure. (Maybe this is the guilty party?)
So, is there a document somewhere which explains why Inkscape cannot underline? I looked for a while but all Google turned up were lots of threads about how Inkscape does not have underline, but not _why_ it does not.
