[poppler] pdftohtml : enhancing it to use embedded fonts

[suzuki toshiya]

I guess, what Leonard said would be: Type42 font format does not
require to preserve "OS/2" table, so PDF or Type42 embedded font
cannot convey the permission info. Although PDF is new technology
and I wish if it can hold such info, the lack of such info in
Type42 is reasonable, because it might have been designed when
most TrueType didn't have OS/2 table.

I will check if there is more appropriate way to convey the info.
