Bug 705831: pdfwrite drop not required TTF tables.
Unlike the Postscript code, pdfi does not have a create a Type 42 font from a
TTF stream, it can just use the TTF stream unchanged. This means pdfi does
not "filter out" TTF tables not required for Type 42, and pdfwrite would then
write out (almost) all the tables presented to it, meaning the output file size
could increase significantly.
This just has pdfwrite filter out TTF tables not used in TTFs embedded in PDF
files.
