zqzhang@, does this still apply?

I think yes. Sorry I totally missed this.

I guess this no longer applies. Manifest icons now have "purpose" and "platform" members, which are less useful for media icons. We probably need to split the two structures.

Split MediaMetadata::MediaImage from Manifest::Icon

Now Manifest::Icon has new members that doesn't apply to MediaImage. We
should split the two structs.

The structs are split as Manifest::Icon now have new fields.
There's consideration of converging the icon structs from various Web APIs, but I think it should track this on spec issues instead of here.
