This is the generic interface for bit stream reader agents. A bit stream reader agent is an entity that allows reading from a bit stream and requesting compressed code-blocks. It can be a simple file reader, or a network connection, or anything else.

The bit stream reader agent allows to make request for compressed block data in any order. The amount of data returned would normally depend on the data available at the time of the request, be it from a file or from a network connection.

The bit stream reader agent has the notion of a current tile, and coordinates are relative to the current tile, where applicable.

Resolution level 0 is the lowest resolution level, i.e. the LL subband alone.
