/**
 * Standard AWT Constants
 *
 * Use the static accessor method (getConstants()) to get the appropriate 
 * constants instance for the registry. This is done so that until the
 * the constants are needed, they aren't registered.
 *
 * NOTE: Since everything in here just proxies, there is
 *       no need to have them separated by VM. That is why
 *       this in the Proxy package.
 *
 * This is final because this can't be extended. This specific one
 * will be registered with the factory for this key. Any extensions
 * must be done in their own constants and registry key.
