Subject Re: New FFN & Fontable classes

You don't need to create a new doc file. You only have to write the
FontTable to an HWPFFileSystem, then use that same file system to create the
new FontTable. Look at the following code (assume that you already have a
FontTable object):

HWPFFileSystem sys = new HWPFFileSystem();

fontTable.writeTo(sys);

HWPFOutputStream tableStream = sys.getStream("1Table");

FontTable newFontTable = new FontTable(tableStream.toByteArray(), 0,
tableStream.getOffset());

//end of example

Also, you handle writing to the FIB in your FontTable class. Don't do this
because this will be handled somewhere else. You pass in an fcMin to the
writeTo function. This argument is unnecessary.
