Detailed Description

A FacePrinter is capable of performing low-level printing operations to some assigned (physical or 'virtual') face.

It contains up to four function pointers describing how to:

1. Print a single byte to a(n incomplete) packet,
2. Terminate a (previously incomplete) packet,
3. Print its face code to a(n incomplete) packet, and
4. Provide a zero-terminated name describing this FacePrinter.

The latter two methods are optional and may be null pointers. The first two methods are must either both be non-null (the typical case) or both null (e.g., for a '/dev/null' face that discards all output).
