//   inherited: Whether the property is inherited by default (stated as

//   type: see above
//   alias_for: optional, indicates that the property is an alias for
//     some other property that is the preferred serialization.  (Type
//     must not be CSS_TYPE_LONGHAND.)
//   logical: optional, indicates that the property is a logical directional
//     property.  (Type must be CSS_TYPE_LONGHAND.)
//   axis: optional, indicates that the property is an axis-related logical
//     directional property.  (Type must be CSS_TYPE_LONGHAND and 'logical'
//     must be true.)
//   get_computed: if present, the property's computed value shows up on
//     another property, and this is a function used to get it
//   initial_values: Values whose computed value should be the same as the
//     computed value for the property's initial value.
//   other_values: Values whose computed value should be different from the
//     computed value for the property's initial value.
//   XXX Should have a third field for values whose computed value may or
//     may not be the same as for the property's initial value.
//   invalid_values: Things that are not values for the property and
//     should be rejected, but which are balanced and should not absorb
//     what follows
//   quirks_values: Values that should be accepted in quirks mode only,
//     mapped to the values they are equivalent to.
//   unbalanced_values: Things that are not values for the property and
//     should be rejected, and which also contain unbalanced constructs
//     that should absorb what follows
//
// Note: By default, an alias is assumed to accept/reject the same values as
// the property that it aliases, and to have the same prerequisites. So, if
// "alias_for" is set, the "*_values" and "prerequisites" fields can simply
// be omitted, and they'll be populated automatically to match the aliased
// property's fields.
