1333
1334 If REDRAW is 1, redraw F if the fringe settings was actually
1335 modified and F is visible.
1336
1337 Since the combined left and right fringe must occupy an integral
1338 number of columns, we may need to add some pixels to each fringe.
1339 Typically, we add an equal amount (+/- 1 pixel) to each fringe,
1340 but a negative width value is taken literally (after negating it).
1341
1342 We never make the fringes narrower than specified.
