35 * @brief BoundedParagraphRun
37 * In terms of the bidirectional algorithm, a 'paragraph' is understood as a run of characters between Paragraph Separators or appropriate Newline Functions.
38 * A 'paragraph' may also be determined by higher-level protocols like a mark-up tag.
39 * Bounded-paragraph is a pragraph that have been bounded by explicit tags like a mark-up tag.
40 * Bounded-paragraph could contain multi paragraphs that have been breaked by Paragraph Separators or appropriate Newline Functions.
41 * This will be used to handle information for the attributes of markup tag. Like TextAlign, TextDirection, TextIndent, LineHeight, etc.
