My question is then, what is the action / handler that the editors use for
quick assist? My goal is to use the exact same presentation format the IDE
uses to display the results of my custom IMarkerResolutionGenerator.

Yes, but not in my project's plugin.xml - I have looked through the
plugin.xml files of the various plugins my project references, and I can't
find it. If I could find this, then I could presumably find the action /
handler used by the default editor, and adapt accordingly.
Thanks for patiently bearing with me,
Pepe

OK, finally got all this working on a very rough test basis, and thought
I'd put the code here since Lord knows there isn't much else out there!
1. Hover over ruler shows marker text "Your blablabla don't work."
2. Hover over red-squigglied annotation shows "Your blablabla don't work."
followed by "2 quick fixes available" and 2 quick fix proposals. Clicking
on either proposal shows a "not yet implemented" dialog.
3. Both Control-1 and the right-click context menu inside the SourceViewer
show the 2 quick fix proposals in a white popup and, after a slight delay,
in a yellow popup with further information ("Problem description: Your
blablabla don't work.").
Hope someone finds this useful:
