Patch for hit testing input events

The attached patch adds metadata to GraphicsLayers about scrollable elements within them. When the compositor receives an input event, it is hit tested against these elements. If the test succeeds, the event is delegated to the main thread instead of being processed by the compositor.

The patch also modifies layerTreeAsText() to accept a bitmask specifying the data to output in a similar way to renderTreeAsText().
