Merge to XFA: Refactor progressive renderer.
Hand-application of diffs from https://codereview.chromium.org/1233453014/. This was an oversight, and was too old (pre-reformat) to apply cleanly. Checked against origin/master, only diffs are xfa related. R=thestig@chromium.org Review URL: https://codereview.chromium.org/1416793002 .
