Subject: Protected style fixed in several ways. Method to determine cheaply if
 protection turned on at all. Caret movement doesn't skip over text outside
 protected range. Methods for deciding if a range or the selection contains
 protected text. Several deletion commands perform no action if they would
 delete protected text. Two phase drawing no longer draws invisible text.
