+2010-02-25 add annotation_demo3.py that demonstrates new functionality. -JJL
+
2010-02-25 refactor Annotation to support arbitrary Transform as xycoords
or textcoords. Also, if a tuple of two coordinates is provided,
they are interpreted as coordinates for each x and y position.
Added: trunk/matplotlib/examples/pylab_examples/annotation_demo3.py
