445 visible while the desired glyphs are being built, but becomes
446 invisible before they are updated, then some rows of the
447 desired_glyphs will be left marked as enabled after redisplay is
448 complete, which should never happen. The next time the frame
449 becomes visible, redisplay will probably barf.
451 Currently, there are no similar situations involving iconified, but
452 the principle is the same.
454 So instead of having asynchronous input handlers directly set and
455 clear the frame's visibility and iconification flags, they just set
456 the async_visible and async_iconified flags; the redisplay code
457 calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
458 which sets visible and iconified from their asynchronous
461 Synchronous code must use the FRAME_SET_VISIBLE macro.
463 Also, if a frame used to be invisible, but has just become visible,
464 it must be marked as garbaged, since redisplay hasn't been keeping

557 The former definitions of FRAME_REAL_FOO_TOOLBAR_VISIBLE
558 looked at the toolbar data to see what was there. The
559 current ones look at the current values of the specifiers.
560 This is a semantic change; the former definition returned
561 what was *actually* there right at the moment, while the
562 current one returns what *ought* to be there once redisplay
563 has run to completion. I think this new definition is more
564 correct in almost all circumstances and is much less likely
565 to lead to strange race conditions. I'm not completely
566 sure that there aren't some places in the redisplay code
567 that use these macros and expect the former semantics, so
568 if you encounter some odd toolbar behavior, you might want
569 to look into this. --ben */
