Subject: fix QTextFormat::FullWidthSelection for right-to-left text layouts
Using the QTextFormat::FullWidthSelection property to select a line
would previously not take into account right-to-left text layouts.
With this patch, the whole line should now be drawn correctly for both
left-to-right, and right-to-left layouts.
