jp2_family_src::open

With this form of the overloaded open function, the JP2 source data is recovered from the supplied caching data source. In this case, jp2_input_box objects opened directly or indirectly using the present object may have contents which grow dynamically as the cache contents expand. Moreover, in this case the jp2_input_box::get_capabilities function associated with any open contiguous code-stream box will advertise the KDU_SOURCE_CAP_CACHED attribute, while all other box types will advertise KDU_SOURCE_CAP_SEQUENTIAL and KDU_SOURCE_CAP_SEEKABLE.
