OK for now, but interestingly, we're probably going to have to modify this
function to accept some js-specific arguments now that JS can't find its own
code anymore ( see https://code.google.com/p/chromium/issues/detail?id=439793 ).

i'm curious, why do that instead of initializing v8 directly from src/pdf? i.e.
third_party/pdfium already doesn't initialize v8 itself, and depends on the
wrapper code to do so.
