Initial OpenType + SVG compression results w/ WOFF 2.0 (Brotli)

Hello Chris, and working group,

During the conference call yesterday, Chris suggested determining how
well the new SVG in OpenType (color fonts) would compress with WOFF
2.0 (Brotli).
http://www.w3.org/2013/10/SVG_in_OpenType/

Here are some early results, to start exploration.  For the first test
font, we see ~15% better compression with WOFF 2.0 (Brotli) over WOFF
1.0 (GZIP).

Details:

>From the above site, I downloaded GeckoEmoji.ttf.  Then converted the
font to WOFF 1.0, 2.0.

Original size:    1,320,708 bytes
WOFF 1.0 size: 521,064 bytes  (GZIP compression), ~60% smaller than the original
WOFF 2.0 size: 439,028 bytes  (Brotli compression), ~66% smaller than
the original, ~15% smaller than the WOFF 1.0 file

For a quick comparison, I compressed the original font with LZMA.  The
resulting font was larger ~6K larger than the Brotli one.  Go Brotli!
