NAME: TitanMovable.lua
DESC: Contains the routines to adjust the Blizzard frames to make room for the Titan bars the user has selected.

DragonFlight introduced an Edit Mode for the user to move various frames where they want them.
However two UI elements were not included:
- XP / Status bar (with the reputation bar above)
- menu & bag buttons

This greatly chanegd the work Titan needed to do.
Now Titan only needs to allow the user to manually adjust the two UI elements themselves.

:DESC

NOTE:
- All secure hooks were removed from Movable.
- All timers were removed from Movable.

VAR: framePosition - TITAN_PANEL_PLACE_TOP or TITAN_PANEL_PLACE_BOTTOM
OUT: Y axis offset, in pixels
NOTE:
- As of DragonFlight this may not be as useful. Leaving to not break any addons.

- The preferred method to determine the Y offset needed to use TitanUtils_GetBarAnchors()
which provides anchors (frames) for an addon to use.
