Doesn't work for me, as I don't want to use a GUI but save my plots as 
images.

blit() raises an error:
AttributeError: 'FigureCanvasGTKAgg' object has no attribute '_pixmap'

Probably because the FigureCanvasGTK part of FigureCanvasGTKAgg is not 
initialized?!

I guess I need blit() implemented in FigureCanvasAgg, but to my 
understanding of the animation/blitting stuff, this is probably not how 
  "lowlevel" figurecanvas like FigureCanvasAgg work, as they are vector 
based.

I solved my initial problem with a kind of very simple coastlines-cache 
in the basemap toolkit. I will discuss my changes with Jeff Whitaker, 
maybe they will find their way into basemap eventually...
