Sets the amount of spacing in Pango units between the lines of the layout.
When placing lines with spacing, Pango arranges things so that
line2.top = line1.bottom + spacing
The default value is 0.
Note: Since 1.44, Pango is using the line height (as determined by the font) for placing lines when the line spacing factor is set to a
non-zero value with [[email protected]_line_spacing]. In that case, the spacing set with this function is ignored.
Note: for semantics that are closer to the CSS line-height property, see [[email protected]_line_height_new].
