// DumpFile is suitable for both dumping an entire file structure to screen _as well as_ access to 
// specific to specific legacy fields (as much required for auto-testing). 
// 
//  Currently supports
//     - JPEG
//     - TIFF 
//     - PHOTOSHOP
//     - JPEG2K
//     - WMAV (ASF/WMA/WMV)
//     - IFF/RIFF (AVI/WAV/RF64/AIFF/AIFF-C)
//     - PNG
//     - InDesign
//     - MP3
//     - MOV (Quicktime)
//     - UCF (done, including commented zips and zip64 (>4GB))
//     - SWF
//     - FLV
//     - MPEG-4
//
// DumpFile does depend on XMPCore and the packetscanner from XMPFiles.

	// AVI and WAV files are RIFF based. Although they have usage differences, we can have a common
	// dumper. This might need changes for other RIFF-based files, e.g. for specific legacy
	// metadata. RIFF is a chunky format. AVI and WAV have an outermost RIFF chunk. The XMP is in a
	// top level "_PMX" chunk. Legacy metadata for WAV is in a top level LIST/INFO chunk.  Legacy
	// metadata for AVI is in a variety of places, don't have specs at present. Free space can be
	// JUNK or JUNQ.
	//
	// A RIFF chunk contains:
	//   - A 4 byte chunk ID, typically ASCII letters
	//   - A little endian UInt32 size of the chunk data
	//   - The chunk data
	//	 - Pad byte if the chunk data length is odd (added on 2007-03-22)

	// The ID is written in "reading order", e.g. the 'R' in "RIFF" is first in the file. Chunks
	// must start on even offsets. A pad byte of 0 is written after the data if necessary. The size
	// does not include the pad, nor the ID and size fields. Some chunks contain nested chunks,
	// notably the RIFF and LIST chunks do. These have the layout:
	//   - A 4 byte chunk ID, typically ASCII letters
	//   - A little endian UInt32 size of the chunk data
	//   - A 4 byte usage ID, typically ASCII letters
