Hi Arnd, John, all,

Thanks for the profiling information on WX and WXAgg backends, and
sorry I haven't been able to participate in this conversation
more.  I've been running experiments for several weeks, and am
definitely looking forward to a break!  Hopefully I'll be able to
devote some time to this in January.

I'm really not a wx or matplotlib expert, buit I am definitely
interested in getting WX or WXAgg to go faster.  Re-drawing line
scans at 15Hz would be plenty fast enough for my needs but I would
like that to include rescaling the axes as well as updating the
line (which is what most of the current benchmarks test).  
Refreshing relatively small images at 1Hz would be OK for me - I
think that's already good enough for me.  Also, I'll have to admit
my timeframe is probably going to be slower than many people on
this list!  So if you or someone else wants to jump in, that would
be fine with me.
  
I agree that the Agg rendering itself does not seem like the
bottleneck for WXAgg.  Partly because of that, I'm assuming that
the WXAgg will be good enough for my needs (as opposed to
completely rewriting backend_wx) and that getting to GTKAgg level
of performance would be the goal.  I also agree that the best
solution is likely to mean converting the Agg image (pixBuffer??)
into the wx.bitmap in c++.  I'm not sure I have a firm grasp on
how exactly to do that, but it's worth trying.
