/* RTF/RTFD methods. If dict is not NULL, the init methods return a dictionary with various document-wide attributes. Similarly the RTF creation methods take an optional dictionary to allow writing out document-wide attributes. Currently supported attributes are @"PaperSize", @"LeftMargin", @"RightMargin", @"TopMargin", @"BottomMargin", and @"HyphenationFactor". The first one is an NSSize (in an NSValue), and the rest are all floats (in NSNumbers).
/* Methods to "fix" attributes after changes. In the abstract class these are not called automatically. The range arguments are the ranges in the final string.
