[OpenType] Windows 8.1 color fonts

[Sairus Patel]

It would be premature to compare the various approaches given we don't
have all proposals for review yet. So for now let me point out that the
SVG-in-OT approach has the following features:

- Spot color, gradients, and other aspects of a rich graphics model
- Animation
- Pre-existing W3C/HTML5 standard for the above model (SVG)
- Dynamic (i.e. Render-time) "Color by numbers" feature
- Collaborative, open process. Participation/feedback from the OT/OFF
community welcomed during all parts of its development

The approach has been: If we're going to do something this new in OF/OTT,
let's do with a rich, already existing graphics model so that
implementations don't have to roll their own.

An updated proposal that reconciles Mozilla's and Adobe's approach, and
includes other feedback received, will be sent out for review in the
upcoming weeks.
