(Search first to make sure that allowing the user to choose between
multiple formats is not discussed before!)

I don't think that's a good idea.  For starter, allowing the user to
choose between two (or more) formats when taking screen-shots will go
against the philosophy behind GNOME Human Interface Guidelines (i.e.
Make It Simple and Straightforward "KISS".)  Simply, it'll confuse
non-expert users.  PNG is good enough in most cases (yes, off course,
there's always exceptions just like this one!).

Second, the problem here is not "gnome-screenshot" is not doing a good
job, it's, to the contrary, doing it very excellent (by including the
background of the Desktop)!  What is wrong here is that the user (you in
this particular case) taking the screen-shot for the whole Desktop
instead of the things you really want!  A better solution would be to
take *two* separate screen-shots of the two windows appearing in your
original screen-shot!  (By the way, I'm really getting tired and
irritated of the repeated "screen-shot" in my post!)

I'm sorry for this long post (and as you might guessed it already,
English is not my native language which make me choose a long, boring,
off-the-point sentences instead of short, direct, and to-the-point
Again, sorry for this long message and remember:  I might be right or
wrong!  This is just my opinion!
