I modified some code to test two cases.
* directly call the readNextChunk() in the guacamole client.
* call the guac_protocol_send_ack() in the clipboard module of the guacamole
server.
So, when copying the image with a large size from the client to the remote
computer, the speed of transferring clipboard data is different according to
whether directly call readNextChunk() without "ack" response or call
readNextChunk() based on "ack" response.
*That's, the former case is faster than the latter case.*

> !image-2020-11-17-09-27-14-470.png!
> So, only the 6048 bytes are sent in the whole data.
