Drawing of plots with multiple matplotlib.Text instances is so slow as to be unusable for some applications, such as realtime multiple sequence alignment rendering/viewing (see attachment for a pylab example, resize plot window to see effect).
Some layman's thoughts:
- Would it be possible to speed things up by implementing some kind of Text Collection?
- Is antialiasing involved? An option to turn it off would be nice in that case.

It appears that the text is re-rendered to a newly allocated buffer each time the text is drawn. Perhaps some caching of text elements would help.
(Mostly just making a note of it for someone else to work this through, or until I have the time.)
