I don't agree here.  I think lots of programs either copy a lot of the
do_* functions from parted.c or would like to do so.  The current API is
still not as high-level as it should be.

So this would probably include the functins snap_to_boundaries, snap,
prefer_snap, constraint_from_start_end,
constraint_intersect_and_destroy from parted.c.

I guess this is already possible; I am not sure, though.

  Apart from the things mentioned, another thing is important which also
affects GParted: a stable and well-thought API to interface with
external programs.  The addition of this to libparted would enable it to
resize a lot of file systems and interface with utilities like dd or
badblocks.  The GParted code that does this will probably become
obsolete with this.  We could work together on the specification of this
API since I'm perfectly sure you know about the requirements of it.
