00009 // data components accessible via a VisBuffer.  Its current usage is to
00010 // specify the VisBuffer components to be prefetched when asynchronous I/O
00011 // is in use or to specify the VisBuffer components that have been modified
00012 // when a Visibility Processing Framework bucket-brigade is operating on
00013 // a VisBuffer.  This implementation should be replaced by a C++11 when
00014 // the standard matures a bit.
