Note that jit-lock doesn't care about any "parameters".  It fontifies
whatever redisplay or a timer triggered function ask it to fontify.

With jit-lock you don't determine "the region to fontify".  You only
determine regions that might need (re-)fontification when they are
redisplayed or - with stealth fontification - emacs is idle.
