[XeTeX] \font "<platform font>":color=FFFFFF produces black, not white glyphs

[Zdenek Wagner]

Professional Acrobat contains Prepress Tools that can verify PDF and fix
quite a lot of problems. It costs money but a damaged book may cost even
more. And there is also a PitStop plugin that may be useful. Many print
houses have it and complain if the supplied PDF does not conform to PDF/X.
