__RFB onFBUReceive and on FBUComplete callback details__
The onFBUReceive callback is invoked when a frame buffer update
message has been received from the server but before the RFB class has
done any additional handling. The onFBUComplete callback is invoked
with the same information but after the RFB class has handled the
message.
The 'fbu' parameter is an object with the following structure:
{
x: FBU_x_position,
y: FBU_y_position,
width: FBU_width,
height: FBU_height,
encoding: FBU_encoding_number,
encodingName: FBU_encoding_string
}
