What do you mean by "which face" (singular)? Redisplay of a typical buffer under a major mode such as CC Mode usually needs to use and merge about a dozen of different faces (think font-lock), so there isn't a single face to figure it out. Maybe you mean the default face? That one gets computed whenever we start the display operation, such as redisplaying a window, and is reused until we are done with the window. Then we compute it again when (or if) we go to redisplay another window.
