jp2_input_box::get_capabilities

Overrides kdu_compressed_source::get_capabilities

Returns the logical OR of one or more capability flags, whose values are identified by the macros, KDU_SOURCE_CAP_SEQUENTIAL, KDU_SOURCE_CAP_SEEKABLE and KDU_SOURCE_CAP_CACHED. These flags are defined in connection with the base class's virtual member function, kdu_compressed_source::get_capabilities, which is implemented here.

Note that KDU_SOURCE_CAP_CACHED can only be offered by contiguous code-stream boxes, and only if the original jp2_box_src object from which this box was opened (directly or indirectly) was opened with a kdu_cache object as its information source.
