451 visible while the desired glyphs are being built, but becomes
452 invisible before they are updated, then some rows of the
453 desired_glyphs will be left marked as enabled after redisplay is
454 complete, which should never happen. The next time the frame
455 becomes visible, redisplay will probably barf.
457 Currently, there are no similar situations involving iconified, but
458 the principle is the same.
460 So instead of having asynchronous input handlers directly set and
461 clear the frame's visibility and iconification flags, they just set
462 the async_visible and async_iconified flags; the redisplay code
463 calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
464 which sets visible and iconified from their asynchronous
467 Synchronous code must use the FRAME_SET_VISIBLE macro.

470 it must be marked as garbaged, since redisplay hasn't been keeping

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