12b2d09a87 Remove obsolete TODO item 
We don't cache any metrics internally, so the correct way to add more
glyph metrics items is to add new callbacks for them.  We already have
separeate callbacks for advance vs extents.

Behdad Esfahbod
39dede9fff Make sure boolean features always use value=1 
Previously boolean features turned on the entire feature mask.  This is
wrong if feature is Alternate and user has provided values bigger than one.
Though, I don't think other engines support such corner cases.

852912fc2d Fix applying default-value for features 
Previously if a default global feature was overrided by a non-global
user feature, we were not setting any default mask for the feature,
essentially disabling the feature by default.  Fix that.
