The code that does this on Mac OS X WebKit starts in -[WebView  
setDrawsBackground:]. I'm not sure what all it ends up doing, but it  
shouldn't be too hard to follow that code around and see what ends up  
happening at the WebCore level.

Like many things in WebKit, much of the logic could probably be moved  
down into WebCore so it could be used on additional platforms.
