Shrinking Fatness: Reduce the Size of PPTX files.

Me Bitching (you may want to skip to the end for the fix)

The newest version of Microsoft PowerPoint 2007 (2008 for the Mac) writes to the new file extension .pptx which supposedly gives it advantages over the old .ppt style. I've had to work with PowerPoint files made with Office 2007 a lot recently and I've noticed that the file size of the PPTX kept growing and growing. Pretty soon the file had grown to 22 MB from the original 3 or 4 MB.
