// A CSSName is a Singleton representing a single CSS property name, like
// border-width. The class declares a Singleton static instance for each CSS
// Level 2 property. A CSSName instance has the property name available from
// the ToString method, as well as a unique (among all CSSName instances)
// integer id ranging from 0...n instances, incremented by 1, available using
// the public field FS_ID (e.g. CSSNameColor.FS_ID).
//
// Initialization order. The Java class runs three steps in its static
// initializer, in this order: (1) one addProperty call per property, each
// with a new property builder; (2) filling ALL_PROPERTIES; (3) parsing the
// initial value of every implemented primitive property with a CSSParser and
// deriving a value from it with DerivedValueFactory. Go initializes
// package-level variables in an order it derives from their dependencies and
// runs init functions after that, so the steps are arranged as follows.
//
//   - Step 1 without the builders happens in the initializers of the
//     CSSName... variables below. cssNameAddProperty depends on nothing
//     outside this file, so the variables are initialized in declaration
//     order, which is the Java order, and every FS_ID is the same as in Java.
//     Package-level variables of other files that refer to a CSSName (the
//     CSSName arrays of the shorthand property builders) get the pointer,
//     with propName, initialValue, the flags and FS_ID set. Step 2 happens in
//     the same call: the property is appended to cssNameAllProperties, where
//     its index is its FS_ID.
//   - The builders are attached by the init function of this file, in the
//     Java order. Were the builder constructors called from the variable
//     initializers, a constructor that refers to a CSSName or to anything
//     initialized from one would reorder the initialization and change the
//     FS_ID values, or fail to compile with an initialization cycle.
//   - Step 3 runs on the first call of InitialDerivedValue, once for all
//     properties, in the Java order (sorted by property name). It needs the
//     CSS parser, the property builders, StylesheetInfo and
//     DerivedValueFactory to be initialized, which is not the case while this
//     file's package-level variables or init function run.
