Revision 197527

New FontInfo class (original design was from Layout.FontInfo, and was removed
and placed into the Document class last year).  This class is to be an encapsulation
of the Font information within apps.Document, also to be used in Transcoder and other
non-XSL-specific classes and packages instead of an apps.Document object, in those
cases where the latter either presents too much information and/or is not relevant
for referenced class' task.  Currently not used, pending new patch in Bugzilla.
