Extension for the tooltip library wz_tooltip.js.
If a tooltip is created with TagToTip(), this extension inserts the DOM node
itself into the tooltip, rather than just a copy of the node's inner HTML.
*/

// Here we define new global configuration variable(s) (as members of the
// predefined "config." class).
// From each of these config variables, wz_tooltip.js will automatically derive
// a command which can be passed to Tip() or TagToTip() in order to customize
// tooltips individually. These command names are just the config variable
// name(s) translated to uppercase,
// e.g. from config. TagToTipDirect a command TAGTOTIPDIRECT will automatically
// be created.

//===================	GLOBAL TOOPTIP CONFIGURATION	======================//
config. TagToTipDirect = false		// true or false - default is false, as we don't want this to be the default behaviour
//=======	END OF TOOLTIP CONFIG, DO NOT CHANGE ANYTHING BELOW	==============//


// Create a new tt_Extension object (make sure that the name of that object,
// here ttte, is unique amongst the extensions available for wz_tooltips.js):
var ttte = new tt_Extension();


// Implement extension eventhandlers on which our extension should react
ttte.OnLoadConfig = function()
{
	if(tt_elToTip && tt_aV[TAGTOTIPDIRECT])
		return true;

	return false;

ttte.OnCreateContentString = function()

		// Store the tag's parent element so we can restore that DOM tree
		// branch when the tooltip is hidden
