This is cited as a "hack for GDI -- do not use if you can help it" by
third_party/skia/include/core/SkFont.h. Put a comment here citing that we should
remove this hack when we switch to DirectWrite on Windows; but maybe we can't
actually remove it entirely until we drop support for Windows machines without
DirectWrite support (Win XP and maybe some Vista systems only have GDI, afaik).
