Poor anti-aliasing when using pdfium_test

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use pdfium_test to convert the attached pdf to a ppm
2. Open the ppm and extreme jags are present in the frame around the image

What is the expected output? What do you see instead?
When viewing the attached pdf in Chrome the edges are smooth, but when using 
pdfium the edges are jagged. 

What version of the product are you using? On what operating system?
pdfium head

Please provide any additional information below.
I have attached a png version of the ppm.

It's jagged in Chrome as well. Either Chrome regressed or it was never 
anti-aliased there in the first place.
