They are not relocatable.

Think device independence.... Use points, not pixels.

The graphic should be placed at an absolute location.  With it fixed
in place the %%BoundingBox comment accurately describes its position
and size.  If you then want to include this image into another image,
you can use the BoundingBox info to do the appropriate translate,
scale, and rotate.  These three operators are all that you need to get
the included image in the right spot with the proper size and
orientation.  Its generally a good idea to put a save and restore
around the image.  A clip region may also come in handy.
