Revert postscript code removal.
Revert CL http://crrev.com/2608663003 in preparation for adding
postscript generation to Pdfium.
Note postscript generation code will not be called until additional
patches land. These patches will also include modifications needed to
make this code functional (currently missing a few compression functions).
