Edit Path mode lets you interactively adjust the axes of an existing path
in order to change its direction or shape.  A path's axis determines how
objects that will follow it, will move.  The Y alignment of a path axis
determines the direction in which the path proceeds; movement along the
path occurs in a positive Y direction.  Rotating an axis along X will
change the pitch (incline or decline) of the path at that point.
`Rotating`an axis along Z changes the turn, or heading, of the path.
`Rotating`along Y, changes the bank of the path.
