Eyedropper needs to sample the flattened color, not the object that I click on
Many many times, when I use the eyedropper, I wish that it was sample the actual color of what I am seeing on the screen, rather than whatever the top object is that I have clicked on. For example I might have a number of layers of transparency, or I might want to click a particular value in a gradient, but the result only gives me the color of the object that I clicked on. Is there a way that you could hold down a modifier key and the eyedropper would instead select the color of the displayed pixel that I clicked on? Incredibly useful!
currently I have to make a screen grab, and then paste it, and then sample from the screen grab. Lame.

Shift will sample the visible colour.
