Is it so? I never found such strong statement in the docs.

1. SVG backend produces vector graphics, no rasterisation in principle, 
so why AGG?
2. Cairo uses its own engine. Why AGG?
3. Image (PNG) "production" from curves, etc. uses AntiGrain, but if 
imshow() shows an image which is just a pixel array, there is no 
manipulation needing AGG, an element (triple RGB) becomes a pixel, and 
that's it.
