Set and read the XdndActionList property defined in the Xdnd spec. We do

Browse Source 
Thu Jan 21 02:11:44 1999  Owen Taylor  <otaylor@redhat.com>

	* Set and read the XdndActionList property defined
	in the Xdnd spec. We do this always, not just for
	XdndActionAsk like the spec says, but if we don't
	find it, we fall back to actions = suggested_action,
	which is compatible with the language of the spec.
