/* If we simply redrew all visible frames, whether or not they
were garbaged, then this would make all frames clear and
nredraw whenever a new frame is created or an existing frame
is de-iconified; those events set the global frame_garbaged
flag, to which redisplay responds by calling this function.
This used to redraw all visible frames; the only advantage of
that approach is that if a frame changes from invisible to
visible without setting its garbaged flag, it still gets
redisplayed. But that should never happen; since invisible
frames are not updated, they should always be marked as
garbaged when they become visible again. If that doesn't
happen, it's a bug in the visibility code, not a bug here. */
