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. BUG=482253 TEST=none R=vitalybuka@chromium.org Review URL: https://codereview.chromium.org/1115513002 Patch from Scott Byer <scottbyer@chromium.org>.
