If not specified, ASCENT defaults to the value 50 which means that the
image will be centered with the base line of the row it appears in.
If ASCENT is `center' the image is vertically centered with text drawn
in the same face as the image. The point the image is aligned with is
the middle of the height of the face's font. That point is usually
different from the font's base line.
If ASCENT is `center' the image is vertically centered around a
