Test to see if there is text available to be pasted This is done by requesting the TARGETS atom and checking if it contains any of the supported text targets.
This function waits for the data to be received using the main loop, so events, timeouts, etc, may be dispatched during the wait.
This function is a little faster than calling wait_for_text since it doesn’t need to retrieve the actual text.
