This allows us to pass on the related data from CoglScanouts. If dst_rect does not match the mode, we assume that not covered areas are opaque black - usually black bars around a centered surface. While such driver behaviour does not appear to be documented (well) yet, it seems to be followed by all known existing drivers and is used in a similar way in ChromeOS.
