Offending PDF map.

The attached file contains a map diagram from a PDF I recently bought (I got
permission to extract and attach the single page).

It renders extremely slowly - Over a minute of 100% of a core on my core i7
machine. I did a quick comparison with Adobe Reader on my android phone and it
took less than 10 seconds so it's clearly not inherent to the content.

I don't know if this is the same as any of the existing slow rendering bugs as
I don't know how the map is constructed.
