Question about font-lock

Hi all, I am reading font-lock related code, doc, web, this days. And come out some questions about History of font-lock in XEmacs and Gnu Emacs. Would you please help give some light on it if possible? 1. From the doc, font-lock was implement by jwz. Do you know if font-lock algorithm of GNU Emacs still the original jwz's one or had been totally rewrote/refactor already? 2. I see from some web, doc that GNU Emacs jit-lock depends on C level support, are there any detailed document about this dependency except the source code? Do you see how difficult to import the jit-lock and its dependency C support to XEmacs? 3. I find lazy-shot was also said to depends on C level support. I'd not read its source yet. Are you able to describe the difference of jit-lock and lazy-shot in high level? Oh, lost some questions by disturb. will send out when I recall them.
