This directory contains two fun examples that use birds eyes as a
means of navigation over large objects.  Run the graph example with:

	xtentm xd.xt x.xt

on R4 or limited font machines:

	xtentm xd.r4.xt x.xt

This puts up two windows that may be swept using button two.  The area
swept out will be displayed in the larger display window.  All can be
resized, etc.

The other example is a viewer for fax files:

	xtentm xf.xt p.1.tif

It uses pretty much the same code, but displays an arbitrary tif file
instead of a graph.
