! /* Produce glyphs for the display element described by IT.  *IT
!    specifies what we want to produce a glyph for (character, image, ...),
!    and where in the glyph matrix we currently are (glyph row and hpos).
!    produce_glyphs fills in output fields of *IT with information such as the
!    pixel width and height of a character, and maybe output actual glyphs at
     the same time if IT->glyph_row is non-null.  See the explanation of
!    struct display_iterator in dispextern.h for an overview.
! 
!    produce_glyphs also stores the result of glyph width, ascent
!    etc. computations in *IT.
! 
!    IT->glyph_row may be null, in which case produce_glyphs does not
!    actually fill in the glyphs.  This is used in the move_* functions
!    in xdisp.c for text width and height computations.
! 
!    Callers usually don't call produce_glyphs directly;
!    instead they use the macro PRODUCE_GLYPHS.  */
