Summary [BlackBerry] Don't use WebKit thread scale information in WebPageCompositor

WebPageCompositor and the related BackingStore member function compositeContents() are using WebKit thread data on the user interface thread, without synchronization primitives or anything. That's bad and should be fixed. Potential threading problems can be avoided by moving from WebPage members and mapToTransformed() to the web page client's userInterfaceViewportAccessor(). As part of this cleaning effort, the WebPageCompositor's render() method is changed to now take document instead of pixel coordinates.
