--- Similar to cubeapply, except that it takes 2 positions and only keeps an ellipsoid-shaped area defined by the boundaries of the defined region.
-- Takes a backup copy of the defined region, runs the given function, and then
-- restores the bits around the edge that aren't inside the largest ellipsoid that will fit inside the defined region.
-- @param {Position} pos1 The 1st position defining the region boundary
-- @param {Position} pos2 The 2nd positioon defining the region boundary
-- @param {Function} func The function to call that performs the action in question. It is expected that the given function will accept no arguments.
