A newline can have a @code{line-spacing} text or overlay property that
controls the height of the display line ending with that newline. The
property value 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.
If @var{line-spacing} is a floating point number or cons, the
additional vertical space is the product of @var{line-spacing} and the
default frame line height.
If the @var{line-spacing} value is a cons @code{(total .
@var{spacing})} where @var{spacing} is any of the forms described
above, the value of @var{spacing} specifies the total displayed height
of the line, regardless of the height of the characters in it. This
is equivalent to using the @code{line-height} property.

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.
