Make draw plane selection for curves be unrelated to 3d Track (somewhat related to #2825).

* Makes more sense user wise and makes for better code.
* Helps refactor code to relate grids to curves so the curves can have access to the grid
   it is being drawn on.
* This will help fix #2825 by being able to project curve points onto the exact triangle geometry.
