I'm actually not looking at it as a problem to be solved at all, but = rather as a blue-sky project to investigate what might be possible with = new display toolkits. By way of example, in past discussions about = using systems like (but not exactly) khtml, gecko, or gnome's canvas = with emacs, it was suggested that emacs had certain requirements that = such systems could not meet. My guess is that while this is still true = to some degree, there might be new systems that could get along with = emacs' needs, and that might offer features not currently available to = emacs. Since my above wording might have been unclear, let me try again: I = expect that this request will demand too much time and effort to be = viable for the people that already have the expertise required. I was = hoping for some partial effort, such as a document, discussion thread, = or short ``as I remember it'' essay that might provide a good starting = place. I was expecting (since this is potentially a lot of effort for a = blue-sky project) something more akin to your ``start by thoroughly = studying the current display engine''.
