static

!! verify single dbuf

Get node we are going to decode from the CompressedVector's prototype

Get pointer to parent ImageFileImpl, to call bitsNeeded()

!! need to pick smarter channel buffer sizes, here and elsewhere Constuct Integer decoder with appropriate register size, based on number of bits stored.
