474 visibility changes at arbitrary times. For example, if a frame is
475 visible while the desired glyphs are being built, but becomes
476 invisible before they are updated, then some rows of the
477 desired_glyphs will be left marked as enabled after redisplay is
478 complete, which should never happen. The next time the frame
479 becomes visible, redisplay will probably barf.
481 Currently, there are no similar situations involving iconified, but
482 the principle is the same.
484 So instead of having asynchronous input handlers directly set and
485 clear the frame's visibility and iconification flags, they just set
486 the async_visible and async_iconified flags; the redisplay code
487 calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
488 which sets visible and iconified from their asynchronous
491 Synchronous code must use the FRAME_SET_VISIBLE macro.
493 Also, if a frame used to be invisible, but has just become visible,
494 it must be marked as garbaged, since redisplay hasn't been keeping

587 The former definitions of FRAME_REAL_FOO_TOOLBAR_VISIBLE
588 looked at the toolbar data to see what was there. The
589 current ones look at the current values of the specifiers.
590 This is a semantic change; the former definition returned
591 what was *actually* there right at the moment, while the
592 current one returns what *ought* to be there once redisplay
593 has run to completion. I think this new definition is more
594 correct in almost all circumstances and is much less likely
595 to lead to strange race conditions. I'm not completely
596 sure that there aren't some places in the redisplay code
597 that use these macros and expect the former semantics, so
598 if you encounter some odd toolbar behavior, you might want
599 to look into this. --ben */
