       way is significant.  Note that if you add a flag, there are numerous
       places in extents.c that need to know about it.

       Another consideration is that some of these properties are accessed
       during redisplay, so it's good for access to them to be fast (a bit
       reference instead of a search down a plist).

       `begin_glyph_layout' and `end_glyph_layout' are unusual in that
       they have 4 states instead of 2.

       Other special extent properties are stored in an auxiliary
       structure that sits at the beginning of the plist.  The has_aux
       flag indicates whether this structure exists.  The has_parent
       flag is an optimization indicating whether the extent has a parent
