Title: Basic object packing

This is the first pass at packing. `chain_pack(objects, buffer)` will chain
transforms on all objects in `objects` so that they are in a straight line
in the center aligned on the X axis.

The transformations are not automatically applied.

The `-p` command line option enables packing
The `-b ` changes the default padding of 5.0
