Why not just ChromeUtilityMsg_RenderPDFPagesToMetafile ?

[scottmg, 2014/05/14 00:34:48]

A few (not great) reasons:
- I don't know how many pages are in the pdf to create the vector<PageRange>
- IPC::PlatformFileForTransit
- I was nervous about breaking cloud print as I had a hard time testing it.

Maybe an empty PageRange could correspond to all pages in
ChromeUtilityMsg_RenderPDFPagesToMetafile?

Cloud you please put TODO on me, and I'll merge this and cloud print code path.
