icons of floating widgets in gui

[Torsten]

Hi,

At the moment, all floating widgets have the octave-logo as icon for
distinct assignment to octave in alt-tab- or tasks-panels. The only
exception is the terminal widget (fix here:
https://bitbucket.org/ttl/octave-ttl/changeset/204caff).

What about icons signalling that a window is belonging to octave and at
the same time showing the function of the window (edtior, terminal, file
browser, ...)? For example, the octave logo with the lower right corner
dedicated to the function of the window, i.e. containing the typical
icon for an editor, file browser etc. Only the main window would have
the original octave logo.
What do you think?

Best, Torsten
