[Lazarus] Looking for vectors library

[Leonardo M. Ramé]

Hi, I'm looking for a vector library that should be able to:

1 - Draw over TCustomCanvas descendants.
2 - Draw at least lines, circles and text.
3 - Map world coordinates to screen.
4 - Let me define a viewport on world then draw it to canvas.
5 - Zoom in/out.
6 - It must work in x86-64, i386, Win/Linux.
7 - Open Source.

Does anyone kowns if such library exists?.

P.S.:

I gave a try to AggPas, but it seems to work only on i386.
