This tool draws per-chunk pngs representing the allocation map. A black
or colored dot means the block is allocated.
The output is written to a subdirectory, together with an index.html to be
viewed in a browser.
There are options to control whether color should be used and which block
group types should be printed.
To build, you need to have libpng and libgd installed. It is not part of
the 'all' target, so please build it explicitely with make btrfs-fragments.
A (rather untypical) example can be seen at
http://sensille.com/fragments
Please regard this as a first scratch version and feel free to improve it :)

With the commit 002d021c (committed October 2011)
btrfsctl, btrfs-vol, btrfs-show were declared deprecated.
The last patches related to these commands are dated December 2010.
These tools are replaced by the "btrfs" tool in all the
functionality.
This commit removes all the related code.

Sometimes, when you least expect it, a static binary is what you need to
rescue your data... Or just get a good enough handle on things to make
it work again ;)
"make static" is a gift to you, dear user with filesystem problems!
Anyway, on a more serious note, changed the cflags and ldflags so that
we create a smaller binary, 1.1MB stripped on my 64 bit system
(2.7MB with debug data)
