Werner Almesberger 86c082f5a9 track bounding box also on a per-package basis and use this to scale Postscript
Until now, everything used the bounding box of the root frame which
contains all the packages, visible or not. We now also record what
ends up in which package, allowing inst_get_bbox to return the
bounding box of a specific package.

This is mainly useful for scaling Postscript output where only one
package is printed per sheet and there is not much point in reserving
space for any other packages that may be generated from the same
footprint definition.
