I've moved forward enough with Qt and QtWebEngine that I'm confident 
that it could be used for all the required features: path search for 
manuals and index search.  However, I'm not really happy with the hybrid 
architecture with one part of it in JavaScript, the other part in C++, 
communicating via a web socket.  (The JavaScript part itself 
is in two or three parts that send objects to each other via the "Message API"
to evade browser security restrictions.)  It's an overly fiddly 
architecture.  I have found there is potential for race conditions to 
exist and also performance problems with JavaScript, especially when 
manipulating the DOM.  The existing JavaScript code is useful as a prototype, 
but I think really the entire thing should be written in one language, 
not two.  Apparently with QtWebKit applications had full access to the 
DOM from the C++ side, but with QtWebEngine you are forced to use 
JavaScript.
