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

The only routine is an API call so other addons can determine where Titan Panel is on the UI based on user selection - top and bottom bars only.

NAME: TitanMovable_GetPanelYOffset
DESC: Get the Y axis offset Titan needs (1 or 2 bars) at the given position - top or bottom.
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.
