I just took 2 minutes looking at the source code for scrot (which is
about as simplistic a screen grabber as you'll find), and it looks
fairly simple: it uses giblib, which provides a function called
gib_imlib_create_image_from_drawable, which does exactly that. Not sure
if Haskell bindings for giblib exist already though.
