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.
Since 1.12
