gimp/devel-docs/tools

The doc-shooter is a small utility used to create screenshots of
widgets for the GIMP API reference manuals.  This utility isn't
built by default, you need to explicitely compile it using

 make doc-shooter

Taking the screenshots is also not part of the docs build.
Instead, the images are created, and then copied by hand into
devel-docs/libgimpwidgets/images.  Ideally, the images should be
taken once a release, and all images should be updated at the
same time. A simple theme should be used to take the screenshots.

The GTK+ docs team came up with the idea for this utility as
well as some of the code to implement it.
