/* Emacs's redisplay code could become confused if a frame's
   visibility changes at arbitrary times.  For example, if a frame is
   visible while the desired glyphs are being built, but becomes
   invisible before they are updated, then some rows of the
   desired_glyphs will be left marked as enabled after redisplay is
   complete, which should never happen.  The next time the frame
   becomes visible, redisplay will probably barf.

   Currently, there are no similar situations involving iconified, but
   the principle is the same.

   So instead of having asynchronous input handlers directly set and
   clear the frame's visibility and iconification flags, they just set
   the async_visible and async_iconified flags; the redisplay code
   calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
   which sets visible and iconified from their asynchronous
305 306
   counterparts.

307 308 309 310 311
   Synchronous code must use the FRAME_SET_VISIBLE macro.

   Also, if a frame used to be invisible, but has just become visible,
   it must be marked as garbaged, since redisplay hasn't been keeping
   up its contents.  */
