! A newline can have a @code{line-spacing} text or overlay property
! that controls the height of the corresponding display line.
! @c ???  Which display line is "corresponding"?
! The @code{line-spacing} property overrides the default frame line
! spacing and the buffer local @code{line-spacing} variable.  We will
! call the property value @var{line-spacing}.
  
  If @var{line-spacing} is a positive integer, the value specifies
  additional vertical space, below the display line, in pixels.

  @item line-height
  @kindex line-height @r{(text property)}
  A newline can have a @code{line-height} text or overlay property that
! controls the total height of the corresponding display line.
! @c ???  Which display line is "corresponding"?
  We will call the property value @var{line-height}.
  
! If @var{line-height} is 0, the newline does not contribute to the
! height of the display row; instead the height of the newline glyph is
! reduced.
! @c ??? That is not clear.  Reduced how much?
! In that case, any @code{line-spacing} property on
! this newline is ignored.  This can be used to tile small images or
! image slices without adding blank areas between the images.
! @c ??? Precisely which of these features does ``this'' mean?
  
  If @var{line-height} is a positive integer, the value specifies the
  minimum line height in pixels.  The line's ascent height is

  We will call the property value @var{line-height}.
