[Xquartz-dev] Proposal for PRIMARY and CLIPBOARD Copy/Paste

You must've missed my earlier email:

Additionally, this particular issue can be solved by making pbproxy  
greedy for CLIPBOARD.  And we have:

On CLIPBOARD is stolen event:
	if option_proxy_clipboard:
		Copy data from CLIPBOARD owner to PB
		if not option_proxy_pb_to_clipboard: // because this is done by the  
PB change event handler if we are
			Copy data from CLIPBOARD owner to pbproxy buffer
			Claim ownership of CLIPBOARD

No, because pbproxy maintains ownership of CLIPBOARD.

> The selection owner is not required to send another XSetSelectionOwner
> request everytime the CLIPBOARD data changes.

Right, but it needs to when it isn't the owner.

Nope, just do it when someone else claims the CLIPBOARD away from  
pbproxy.
