Improved PPTX format decoding

I received a slideshow the other day in a format that the latest
LibreOffice in Debian Sid could not properly read. I have attached it
here to assist the developers interested in reverse-engineering it.

There is some information in this slideshow that is not factual. I have
fixed that in the revision I sent back to the original author. Disregard
the information, please, and use this file to help improve the
LibreOffice experience.

I am not a proponent of the PPTX format, but Impress needs to be able to
read it so that it can be converted to OpenDocument without proprietary

Happy Hacking,
