Wonder why anyone would waste time on implementing functionality which 
is already easily available in VirtualBox...

VBoxManage clonehd /path/to/src.vdi /path/to/dst.img --format RAW

I don't understand the question. VirtualBox can resize a subset images 
of VDI and VHD format, as long as they are not created as "fixed size", 
see the VBoxManage modifyhd documentation.

Let me know what's the use case for raw images... Image formats without 
metadata are annoying to handle, cannot ever represent snapshots 
efficiently, and from my perspective are only relevant for compatibility 
purposes.

Oh, and I wonder if its extra effort to create mails which are SO hard 
to understand because there are typos and editing leftovers everywhere :)
