[Visualpython-users] better graphing

I tried the experiment of using faces instead of label for plotting dots in
visual.graph. It works fine with fixed axes but with variable axes
(automatic rescaling) it is way too slow, due to the need for readjustment
of the faces to keep (for example) a square dot square, whenever there is a
change of scale. The right scheme would be to add a pixel-oriented object to
Visual, to be used for such things as plotting of dots. Note that there is a
precedent: some attributes of the label object are pixel-oriented.
