correct, but as Torsten pointed out a few days ago, he wants to focus on the browser side of things and is not interested in generalizing the concept to also support canvas-based scenarios, so if all the OP wants to do is rendering a map to an instrument, canvas is his best bet currently. If a browser-based solution is also acceptable, I do agree that Torsten's recent httpd/mongoose work should be nice to play with, but both approaches (mongoose vs. canvas) will either require latest binaries from the build server or building the whole thing from source.
That being said, the original question was about "integration" and rendering a map to an instrument - however, google earth also supports various I/O options, and can be linked to FG that way - without exchanging any imagery however....
