	--[[ Here's the story of some taint. A better version is at
		http://www.wowace.com/addons/chinchilla/tickets/177-positioning-scaling-minimap-cluster-taints-other-addons/

		TellMeWhen_Options is getting blamed for tainting the item buttons in the quest log.
		I spent a huge amount of time trying to debug this. What it seems to come down to is that TMW
		is somehow tainting OBJECTIVE_TRACKER_UPDATE_REASON and OBJECTIVE_TRACKER_UPDATE_ID,
		which eventually cascades and taints the var that holds the item for a line in the
		quest tracker, which causes UseQuestLogSpecialItem() to get blocked due to taint.

		This taint is happening through these 3 paths:
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_ObjectiveTracker.lua:995 ObjectiveTracker_Update()
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_QuestObjectiveTracker.lua:115 QuestObjectiveTracker_FinishGlowAnim()
			<unnamed>:OnFinished()
		and
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_ObjectiveTracker.lua:996 ObjectiveTracker_Update()
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_QuestObjectiveTracker.lua:115 QuestObjectiveTracker_FinishGlowAnim()
			<unnamed>:OnFinished()
		and
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_ObjectiveTracker.lua:996 ObjectiveTracker_Update()
			Interface\AddOns\Blizzard_ObjectiveTracker\Blizzard_QuestObjectiveTracker.lua:129 QuestObjectiveTracker_FinishFadeOutAnim()
			<unnamed>:OnFinished()

		There is another way that TMW_Options can introduce taint, but this is only when shift-clicking
		on items in the quest log - TMW's ChatEdit_InsertLink hook taints execution, which will taint ACTIVE_CHAT_EDIT_BOX,
		which then tains execution when calling ChatEdit_GetActiveWindow(), which will cause UseQuestLogSpecialItem() to
		be blocked when holding the shift key (Blizzard_QuestObjectiveTracker.lua:192).

		That taint isn't really the issue, though (its sill an issue, but we don't really care). The issue is
		that regular use of quest items is getting blocked. After hours upon hours of debugging, it turns out that
		for some unknown reason, the loading of TellMeWhen_Options is triggering ObjectiveTrackerFrame's OnSizeChanged to fire.
		This function in turn calls ObjectiveTracker_Update(), and there's a fairly good chance that this will be the first time
		that it is called, so it ends up being TMW_Options that initializes a lot of the quest tracker (if TMW_Options is loading immediately).

		Here's that full call stack:
			[string "TMWOPT_taint debug"]:45: in function <[string "TMWOPT_taint debug"]:43>
			[C]: in function `ObjectiveTracker_Update'
			...zzard_ObjectiveTracker\Blizzard_ObjectiveTracker.lua:700: in function <...zzard_ObjectiveTracker\Blizzard_ObjectiveTracker.lua:699>
			[C]: ?
			Interface\AddOns\TellMeWhen\TellMeWhen.lua:3574: in function `LoadOptions'
			Interface\AddOns\TellMeWhen\TellMeWhen.lua:3164: in function `UpdateNormally'
			Interface\AddOns\TellMeWhen\TellMeWhen.lua:3335: in function `Update'
			Interface\AddOns\TellMeWhen\TellMeWhen.lua:1857: in function `?'
			...Ons\Ace3\CallbackHandler-1.0\CallbackHandler-1.0.lua:147: in function <...Ons\Ace3\CallbackHandler-1.0\CallbackHandler-1.0.lua:147>
			[string "safecall Dispatcher[1]"]:4: in function <[string "safecall Dispatcher[1]"]:4>

			Interface\AddOns\Ace3\AceEvent-3.0\AceEvent-3.0.lua:120: in function <Interface\AddOns\Ace3\AceEvent-3.0\AceEvent-3.0.lua:119>

		It is worth noting that the taint never happens right away. I don't know what exactly triggers it,
		but it never happens until I've been questing for an hour or so. Because the taint is coming from the 
		OnFinished animation script handlers, I suspect I just have to complete a whole bunch of quests until the stars align and it taints.

		After tearing apart a ton of TellMeWhen_Options for several more hours, I eventually came down to a single thing
		that will reliably cause ObjectiveTrackerFrame:OnSizeChanged to fire due to TMW_Options. Brace yourselves for this:

		With a huge amount of TMW_Options code deleted from the includes.config.xml files, it finally came down to adding/removing 
		the configuration panel for the Sound icon event handler. Even if I replaced it with just "<Frame/>" in the xml file,
		the taint still happened. But, after removing it, the taint stopped. Now, this same action DOES NOT affect the taint
		without the very specific set of files that were not being loaded. I have absolutely no clue why this is what was able to "toggle" the taint,
		but it was. After doing further debugging, it ALWAYS happens immediately after that frame is created, but before the next frame is created.

		So, in further attempts to debug what was going on, I thought to add a call to ObjectiveTracker:GetSize() so I could see what the size was BEFORE
		the OnSizeChanged handler was getting called, so I could see if the size really was changing. And guess what? It doesn't get called anymore after
		I added that in. So, that's the story of why the next line of code exists.

	Addendum:
		After a lot more testing, it turns out that this issue always happens at the same time as the first time that TellMeWhen_Options creates
		a frame in xml (doesn't happen when creating a frame in a Lua file). If TellMeWhen_Options is loaded at the very end of this file,
		the issue doesn't happen. If it is loaded in an ADDON_LOADED handlers after TMW finishes loading, it does happen.
		
		It also only happens when my minimap addon (Chinchilla) is loaded, and is allowed to scale and/or re-position the MinimapCluster.

		I've asked Chinchilla's author to add calls to ObjectiveTrackerFrame:GetSize() so that Chinchilla gets blamed for the taint instead of TMW_Options.
		If TellMeWhen calls ObjectiveTrackerFrame:GetSize(), it will just be TellMeWhen that gets blamed for the taint.

	Addendum 2:
		Despite the changes made to Chinchilla, the issue still happens. It doesn't blame TMW_Options every time, though - sometimes
		it will blame other addons instead. I'm not sure that this bug can ever be fixed unless Blizzard lesses the restrictions on UseQuestLogItemSpecial().
