I have a watermark image that I want beneath the content of every  
page. I’d like to use loose objects so I do bloat the file, but loose  
objects seem to always be on top, making for a very poor BACKGROUND  
watermark !

Ok, this seems to work…

#===== shazam

# move the last content item for this page (the loose object)

# to the front pf the content array

#===== shazam  
c = pdf.current\_page.contents  
pdf.current\_page.contents =  
c.slice(-1,1).concat(c.slice(0,c.length-1))
