They would all be useful! If alignment to the baseline is done, that
would be a good time to add other alignments also.
Peter, you might want to take a look at wx.lib.floatcanvas -- the Text
object in there has alignment to top|center|bottom, and
left>center>right -- it was a bit of a pain to write.

If you take a look at my graphic lib http://spinecho.ze.cx/ > jmgraph
there is (also!) a function doing this job.
# Trace un texte au point p. La position relative du texte est donnée

def PlotText(dc, txt, px, py, pos):
Translation:
Draw a text at the point p. The relative position of the text is
given by the string pos. The hotizontal text is drawn from left to
right.
dc, txt: dc, txt to draw
px, py: p point
pos: a 2-chars string indicating the relative position (vert. and horiz.
offsets)
lt: left-top
mt: middle-top
and so on.
If I recall correctly I took that idea from an HP plotter. I do
not remember the used syntax, but the plotter model was HP7475A,
it was ... 20 years ago.
