Using the Xfce4 Screenshooter in combination with Xfce4 compositor works 
beautifully for this as is. I use a darker desktop image or solid color 
as the backdrop to increase the effect of dimming on windows that are 
partially transparent. Tweaking the opacity of various windows, 
decorations, panels, x-terminal-emulator windows, etcetera lets me get 
the desktop to "highlight" exactly what I want highlighted. If I want 
one panel or another highlighted I adjust their transparencies 
accordingly, set the screenshooter's dealy before capturing setting, 
then use the mouse cursor placement to highlight the panel I want to
