Bug 1156742 Part 9: Add a new nsIDeviceContextSpec for proxied printing. r=roc This also changes aPrintToFileName parameter for BeginDocument to an nsAString& from char16_t*. Having a char16_t* caused a pain with VS2105 where wchar_t != char16_t (as on VS2103), after it had been sent over IPDL. This could have been worked around with casting, but this seemed like the tidier solution.
