Substract and intersect pixel selections from layers.

[Grenadine]

Hi!
At the moment in AD we can select all of the layer's pixels by pressing CMD + clicking on the layer's thumbnail. We can also add to current pixel's selection by pressing CMD+SHIFT+Click on the thumbnail.

It would be very convenient to be able to click on a layer in the same way, but this time to substract its pixels, or perform intersection.
(It can get cumbersome to have to create a pixel layer or mask for every one-off selection)

Thank you!
