playout:SetSpacing(spacing)
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 playout:SetLineSpacing().
In that case, the spacing set with this function is ignored.
Note: for semantics that are closer to the CSS line-height property, see the line height Pango attribute.
