WebCore shouldn't need to know anything about window coordinates - especially not in Chromium and WebKit2 where the WebCore widget hierarchy is in a completely different process from the actual window!

We should try to eliminate calls to convertToContainingWindow/convertFromContainingWindow etc and replace them with convertToRootView/convertFromRootView.

The only case where window coordinates are important is in Mac WebKit1 due to the way it works with AppKit, but we should try to keep that code in the WebKit1 code.
