I added an argument, FULLY, to Fpos_visible_in_window_p that uses the window's
desired_matrix to do more careful checking of partial visiblity.

However, in the case where the window layout has been recently changed, with
no intervening redisplay, the desired_matrix is out of date.  I want a way to
update the window's desired_matrix, without doing a real redisplay.
