33 * Server Interaction Capabilities Message (protocol versions 3.7t, 3.8t)

35 * If TightVNC protocol extensions are enabled, the server informs the client
36 * what message types it supports in addition to ones defined in the standard
37 * RFB protocol.
38 * Also, the server sends the list of all supported encodings (note that it's
39 * not necessary to advertise the "raw" encoding sinse it MUST be supported in
40 * RFB 3.x protocols).
41 *
42 * This data immediately follows the server initialisation message.
