* keep a cache of low-res snapshots.
* The snapshot structure is defined in include/snapshot.h
* In order to access the current snapshot cache, object variables are used:
* snapshot-list-pointer : the pointer on the first element in the list
* snapshot-datasize : size of a snapshot
* vout-snapshot-list-pointer : the pointer on the first element in the list
* vout-snapshot-datasize : size of a snapshot
* (also available in snapshot_t->i_datasize)
* snapshot-cache-size : size of the cache list
* vout-snapshot-cache-size : size of the cache list
*
* It is used for the moment by the CORBA module and a specialized
* python-vlc binding.
