Rendering to a SWING surface (e. g. JPanel) using Cairo

I'm currently working on a project where I need to plot the predicted footprint of a satellite on a mercator-projected world map with possible scaling/cropping/etc. done to the map.

I thought Cairo would be a good library to use for this purpose. There are Java-bindings available for it. However, I just can't find a way to make it render onto a SWING GUI (e. g. onto the surface of a JPanel). I thought about rendering into a byte buffer and plotting it out pixel by pixel using Java2D, but I can't find any API call to make Cairo render into a buffer (which is weird, as this is one of the most fundamental functionalities I'd expect to get supported by such a library).

Any way I can achieve this? I know there is Java2D, but it is fairly basic. I'd really appreciate a more powerful, widespread, well-tested, high-quality, free (LGPL) graphics library for this purpose. Cairo would be such a perfect fit, if I could get it to work with SWING somehow.

Thank you very much for your proposals.
