To my knowledge graphic objects were able to detect the mouse inside 
their filled area - instead of their rects - long before 2.7.
I have got a several years old educational sample stack where this is 
implemented and where most graphics in the image overlap each other.

And - while the possibilities of Photoshop and other photo tools surely 
surpass those of Rev in their specific field - I think it to be 
relatively easy to superimpose irregular polygons on images to catch 
mouse events in defined hotspot areas.
Changing the inks of the graphics on mouseenter and mouseleave is 
another variant to "hilite" specific irregular areas in an image.
