Expose additional flags for rasterization.
These flags are unused in Chromium, but are needed for the Cloud Print
conversion process, which takes PDF and produces a raster for low-end
printers. Certain low-end printers (e.g., B&W laser printers) will
turn anti-aliased text into a mess. The existing printing flag isn't
sufficient, as other kinds of printers will still want some kinds of
anti-aliasing to occur for best results.
