     * We have a choice of 3 authentication options

     *   1. none

     *   2. vnc

     *   3. sasl

     *

     * The channel can be run in 2 modes

     *

     *   1. clear

     *   2. tls

     *

     * And TLS can use 2 types of credentials

     *

     *   1. anon

     *   2. x509

     *

     * We thus have 9 possible logical combinations

     *

     *   1. clear + none

     *   2. clear + vnc

     *   3. clear + sasl

     *   4. tls + anon + none

     *   5. tls + anon + vnc

     *   6. tls + anon + sasl

     *   7. tls + x509 + none

     *   8. tls + x509 + vnc

     *   9. tls + x509 + sasl

     *

     * These need to be mapped into the VNC auth schemes

     * in an appropriate manner. In regular VNC, all the

     * TLS options get mapped into VNC_AUTH_VENCRYPT

     * sub-auth types.

     *

     * In websockets, the https:// protocol already provides

     * TLS support, so there is no need to make use of the

     * VeNCrypt extension. Furthermore, websockets browser

     * clients could not use VeNCrypt even if they wanted to,

     * as they cannot control when the TLS handshake takes

     * place. Thus there is no option but to rely on https://,

     * meaning combinations 4->6 and 7->9 will be mapped to

     * VNC auth schemes in the same way as combos 1->3.

     *

     * Regardless of fact that we have a different mapping to

     * VNC auth mechs for plain VNC vs websockets VNC, the end

     * result has the same security characteristics.
