There's a compilation error in DragImageCairoWin.cpp, since Image::size() now returns a FloatSize instead of an IntSize.

I was going to do something similar, but I don't have my windows machine to test it. This seems good to me if it works. I'm not following all this float/int stuff too closely, though.
Thanks for looking into this, guys :)
