Critical areas of the source base to consider are:

* WebCore/rendering (specifically the *Win.cpp implementations).
* WebCore/platform/graphics/mac/GraphicsLayerCA.mm must be ported to the
Windows platform (perhaps as platform/graphics/win/GraphicsLayerWin)

Of special concern is WebCore/rendering/RenderLayerCompositor.cpp, which does
the work of compositing the various elements onto the final surface for
display.  Its implementation makes use of a call "atachRootGraphicsLayer",
which in turn calls the WebHTMLView classes "attachRootLayer" method, which in
turn uses the CoreAnimation "addSubview" method.
