Do we need both? (enums and methods)

[reed1, 2015/01/05 21:58:14]

For now we need filterlevel, until we decided to update existing callers (which
are many).

Should we go ahead and use a #define to stage?

Started too fix all of skia internally, but it is very large, and will make it
hard to separate reviewing that syntactic change from this functional change. I
propose doing that in a follow-on CL.
