Quantizes the thickness and position of a line, typically an
underline or strikethrough, to whole device pixels, that is integer
multiples of %PANGO_SCALE. The purpose of this function is to avoid
such lines looking blurry.
Care is taken to make sure @thickness is at least one pixel when this
function returns, but returned @position may become zero as a result
of rounding.
