Implements the ODF 1.2 paragraph attribute style:writing-mode-automatic, and supporting runtime features. When set, this attribute allows programs to automatically recompute the paragraph writing mode when the contents of the paragraph have been edited. The ODF standard does not suggest any particular algorithm for automatically determining paragraph direction. This implementation uses the rules from Unicode UAX #9 3.3.1. Currently, LO will only automatically change the writing direction when new text is typed or deleted. Other known interesting cases are already tracked as separate enhancement requests.
