commit 212e9060ed
Author: Mike Reed <reed@google.com>
Date: Tue Dec 25 17:35:49 2018 -0500
to try to update it to use SkFont. Along the way we broke the part where
it compares drawing with the typeface pre and post streaming. This CL
restores the original test, and then updated it to use SkFont.
After this CL, we should be able to move SK_SUPPORT_LEGACY_PAINT_FONT_FIELDS
to clients, having them opt-in.
