579 visibility changes at arbitrary times. For example, if a frame is
580 visible while the desired glyphs are being built, but becomes
581 invisible before they are updated, then some rows of the
582 desired_glyphs will be left marked as enabled after redisplay is
583 complete, which should never happen. The next time the frame
584 becomes visible, redisplay will probably barf.
586 Currently, there are no similar situations involving iconified, but
587 the principle is the same.
589 So instead of having asynchronous input handlers directly set and
590 clear the frame's visibility and iconification flags, they just set
591 the async_visible and async_iconified flags; the redisplay code
592 calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
593 which sets visible and iconified from their asynchronous
596 Synchronous code must use the FRAME_SET_VISIBLE macro.
598 Also, if a frame used to be invisible, but has just become visible,
599 it must be marked as garbaged, since redisplay hasn't been keeping

692 The former definitions of FRAME_REAL_FOO_TOOLBAR_VISIBLE
693 looked at the toolbar data to see what was there. The
694 current ones look at the current values of the specifiers.
695 This is a semantic change; the former definition returned
696 what was *actually* there right at the moment, while the
697 current one returns what *ought* to be there once redisplay
698 has run to completion. I think this new definition is more
699 correct in almost all circumstances and is much less likely
700 to lead to strange race conditions. I'm not completely
701 sure that there aren't some places in the redisplay code
702 that use these macros and expect the former semantics, so
703 if you encounter some odd toolbar behavior, you might want
704 to look into this. --ben */
