* From ticket:5923:
*
* Build a paragraph that contains a mixture of left to right and right to left text.
* Break it into multiple lines and make sure that the glyphToCharMap for run in each
* line is correct.
*
* Note: it might be a good idea to also check the glyphs and positions for each run,
* that we get the expected number of runs per line and that the line breaks are where
* we expect them to be. Really, it would be a good idea to make a whole test suite
* for ParagraphLayout.
