OK, I see. I think this could be handled by adding a "click-through" 
property to nodes that would allow you to make the background completely 
transparent to the mouse - you could still make some areas react to the 
mouse by covering them with a hotspot. Or perhaps, more generally, a 
threshold above which alpha value the background should become opaque to 
the mouse - setting that to 1.0 (currently hardcoded at 0.5) would 
achieve the same thing.

How far above half opaque do you need to go? It occurs to me that, as a 
workaround, you could approximate the effect by stacking several 
almost-half-opaque overlays.
