Source/WebKit/blackberry:

The cached draw rectangle is useful for hit testing. Add a getter for
this compositing thread layer property to the public WebOverlay API.
We name this getter using terminology familiar from the
ViewportAccessor interface, to clarify which coordinate system the
getter uses (pixel coordinates relative to the viewport).

Note that WebKit-thread flavor of WebOverlay is not currently used by
any API client and is marked obsolete. It is used internally in WebKit,
but for that case using GraphicsLayer directly works well. This will
allow the complexity of WebOverlay to be significantly reduced in the
future, by removing the WebKit-thread flavor entirely.
