Copy the first *n* foreground voxel values along the axis and direction from the volume to the hull, thus adding foreground voxels to the hull.

)numeric 3d array, the full source volume.
numeric 3d array, the input hull volume.
integer, the array dimension to use. Must be 1L, 2L or 3L.
logical, whether to use upwards direction (increasing indices) in the array dimension
integer, the width of the border in voxels, i.e., how many of the foreground voxels to keep
numeric 3d array, the updated hull volume.
