Link to antigrain.com is not working (Chapter 1, page 8)

Hi @rougier,

I found that the link under "Anti‐Grain Geometry C++ library" to https://antigrain.com is not working, and it is confirmed in the description here, referring also to another site (http://agg.sourceforge.net/antigrain.com/):

The official AGG site remains on Sourceforge, but doesn't see much activity. With www.antigrain.com recently inoperational, I thought a GitHub repo was in order, as the project demos stopped building with the site down.

Thank you.

Thanks. Could you make a PR?

Hi @rougier,

Which link to use instead of https://antigrain.com/ - http://agg.sourceforge.net/antigrain.com/ or https://github.com/ghaerr/agg-2.6?

I think http://agg.sourceforge.net/antigrain.com/ would be best.
