Ok, these are changes internal to MetaObj -- not MetaPost.

After giving it another thought, MetaObj in the current implementation
/should/ benefit from a smarter MetaPost wrt equation handling. The
/creation/ of an object with an attached path should speed up since its
equation system is independent from others at that time.
Internal changes to MetaObj -- such as delaying calculations until a
draw operation -- are welcome, too, of course. :)
