And how matplotlib is written -- there are a lot of layers in there.

There is a key problem though: going from data to a wxImage to a 
wxBitmap that can then be drawn on the screen is pretty slow, partly 
because there is a lot of copying of data done.

Robin is looking into giving wxPython more direct access to wxBitmap 
data, but that may be tricky, as wx.Bitmaps use platform-native data 
formats, which can vary a lot.

Also, there has been chatter on and off about using Agg or Ciaro as the 
basis for the next generation DC. That's a while off, at best, and Cairo 
is slower then Agg, but it would be nice top get all the features.
