This is improved version of previous fix
013c346a8d that was reverted because it
broke some tests for Quick Text. The problem was that it did not work
correctly in the case the text was wrapped to a fixed width.
To deal with this we'll accumulate current line full width (as if it
hadn't been wrapped) in layout data (layoutData->currentMaxWidth).
Then when the next line is explicitly wrapped by line or paragraph
separator, this accumulated width will be used to adjust layout's
maximum width.
