Manages the information associated with JPEG2000
POC marker segment. Tile-specific are allowed, but not
component-specific forms.
The cluster name is "POC", but you are recommended
to use the macro
POC_params, in functions which take a cluster name like
kdu_params::access_cluster.
The following attributes are defined. For an explanation
of pattern strings, consult the comments appearing
with
kdu_params::parse_string.

[MULTI_RECORD] — Progression order change information.
There may be multiple instances of this attribute,
in which case each instance corresponds to a tile-part
boundary. Each instance may contain one or more progression
records, each of which defines the order for a collection
of packets. Each record contains 6 fields. The first
two fields identify inclusive lower bounds for the
resolution level and image component indices, respectively.
The next three fields identify exclusive upper bounds
for the quality layer, resolution level and image component
indices, respectively. All indices are zero-based,
with resolution level 0 corresponding to the LL_D subband.
The final field in each record identifies the progression
order to be applied within the indicated bounds. This
order is applied only to those packets which have not
already been sequenced by previous records or instances.
