* We use an optimization based on Marriott, Stuckey, Tam and He,

* Constraints,8(2):143--172, 2003.
* We solve 2 constraint problem, one in X, one in Y. In each dimension,
* we require relative positions to remain the same. That is, if two nodes
* have the same x originally, they have the same x at the end, and if one
* node is to the left of another, it remains to the left. In addition, if
* two nodes could overlap by moving their X coordinates, we insert a constraint * to keep the two nodes sufficiently apart. Similarly, for Y.
*

* mode = AM_ORTHOYX => first Y, then X
* mode = AM_ORTHO => first X, then Y
* mode = AM_ORTHO_YX => first Y, then X
* In the last 2 cases, relax the constraints as follows: during the X pass,
* if two nodes actually intersect and a smaller move in the Y direction
* will remove the overlap, we don't force the nodes apart in the X direction,
* but leave it for the Y pass to remove any remaining overlaps. Without this,
* the X pass will remove all overlaps, and the Y pass only compresses in the
* Y direction, causing a skewing of the aspect ratio.
*
