Behdad Esfahbod bd7378b2ef Massage mask setting a bit more
Still finding the exact correct way the masks should be set.

Behdad Esfahbod 961f9baa7b Oops, actually set global mask 2010-10-13 17:17:00 -04:00
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.

Behdad Esfahbod 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.
