line-height here, add xref to new "Line Height" node.

 A newline can have a @code{line-height} text or overlay property that
 controls the total height of the display line ending in that newline.
-We will call the property value @var{line-height}.
-
-If @var{line-height} is 0, the height of the line is determined solely
-from its contents; nothing is added.  Any @code{line-spacing} property
-on this newline is ignored.  This case is useful for tiling small
-images or image slices without adding blank areas between the images.
-
-If @var{line-height} is a positive integer, the value specifies the
-minimum line height in pixels.  The line's ascent height is
-increased as necessary to achieve the specified height.
-
-If @var{line-height} is a floating point number, the minimum line
-height is the product of @var{line-height} and the default frame line
-height.
-
-If @var{line-height} is a cons @code{(@var{ratio} . @var{face})}, the
-minimum line height is calculated as @var{ratio} times the height of
-face @var{face}.  The @var{ratio} is an integer or a floating point
-number.  If @var{face} is @code{t}, it refers to the current face.
