Titan adjusts some WoW frames based on the WoW version!
Mainly used for Classic versions where TITAN_ID == "TitanClassic"

DragonFlight introduced an Edit Mode for the user to move various frames where they want them.
Titan no longer needs to do this work for most frames.

There are a small number of frames that WoW does not have in Edit mode. These will be added to the table over time as users request.
The scheme has changed to be more like 'move any/thing' which hooks the SetPoint of the frame.
Titan still only allows vertical adjust - not move anywhere.

- Keeping this simple for now until omplexity needs to be added.
- hooksecurefunc from https://urbad.net/blue/us/34224257-Guide_to_Secure_Execution_and_Tainting
Hooking and the hooksecurefunc function

The taint model is the reason that 'hooking' as it is commonly done today can easily break lots of UI functionality, trying to hook a function that is used by secure code causes a tainted function to be called in the middle of an otherwise secure execution path, this then taints the execution path so that nothing following the hook can use secure functions - don't be too dismayed however, we've been given a tool to get around this.

The new hooksecurefunc API function allows AddOn code to 'post hook' a secure global function, that is run another function after the original one has been run. So for example you could track calls to CastSpellByName using hooksecurefunc("CastSpellByName", mySpellCastTracker). The API replaces the original global function with its own secure hook function that calls the original function, saves its return values away, and then calls your hook function with the same arguments as the original function (any return values from your hook function are thrown away) and then it returns the return values from the original.

The 'special' feature of this secure hook is that when your hook function is executed, it executes with the taint that was present at the time the hook was created, and when your hook function is done that taint is discarded and the original secure (or possibly tainted - you cannot use hooksecurefunc to REMOVE taint, just avoid it) execution mode is restored.

- hooksecurefunc from https://wowpedia.fandom.com/wiki/API_hooksecurefunc.
- The hook will stay until a reload or logout. This means the TitanAdj MUST remain or the normal SetPoint will be broken.
- Setting the hook is cumalitive so add ony once; controlled by titan_adj_hook on the frame.

	Setting the MainMenuBar as user placed is needed because in 8.0.0 Blizzard changed something in the

	This idea of user placed came from a Titan user who is an addon developer.
	However setting user placed causes the main menu bar to not act as we desire due to the way Blizzard coded the bar.
	For now we will try to minimize the side effects...

	Later Titan checks rely on the user placed flag so it needs to be set early.
