/*
* Notes on line spacing
*
* the w:line and w:lineRule attributes control spacing between lines - including between lines within a paragraph
*
* If w:spacing w:lineRule="auto" then
* w:spacing w:line is a percentage where 240 == 100%
*
* (line value / 240) * 100 = percentage of line
*
* If w:spacing w:lineRule="exact" or w:lineRule="atLeast" then
* w:spacing w:line is in twips
* 1440 = exactly one inch from line to line
