The public API of the BlackBerry port always reports a minimum scroll
position of (0, 0), even on RTL pages with left overflow. We
accomplish this by translating the WebCore scroll position by an
amount equal in size to the minimum scroll position, to obtain the API
scroll position reported to the API client.
This means the API client will ask us to render a rect that needs to
be corrected for the minimum scroll position, or we'll render the wrong
parts. This is done for BackingStore, but not for WebPageCompositor.

Since George is the internal reviewer, and this patch is identical to the internal patch, I'll mark him as upstream reviewer, too.
