Richard Zidlicky writes: Very few programs do their own redisplay any more; they delegate to a redisplay like Gecko or webkit, or simply use trivial text areas. The (X)Emacs redisplay is perhaps even more complex than Gecko, since it not only handles redisplay on graphical displays, but also on TTYs. In fact, if you look carefully at Gecko-based programs, you'll see that they do the opposite from XEmacs: when clearing the background for a rectangle, they tend to clip (and not redisplay) surrounding content. It's not clear to me that looking at how other programs do it is going to be all that useful at this point. The problem is the complexity of the XEmacs redisplay. We can't just replace it with something else, because it's intertwined with everything in XEmacs. Instead, IMO it would be best to document, refactor, and simplify the XEmacs redisplay. Hoping that we don't lose performance.... _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-beta
