Move Texture with UV makes a copy of pixels from other layers

[Cubouse]

What are you trying to do, and what do you expect to happen?

Say I am texturing a pizza model.
I have two layers in the Paint tab, and an element. The element's UV overlaps the pixels of the layer named "dough".

In the Paint tab I select the other layer, "toppings". I then go to the UV tab to move the element with Move Texture with UV enabled.

What happens instead?

Even though the layer I had selected in the Paint tab was "toppings", it made a copy and moved the pixels of the layer "dough" on the "toppings" layer (and also left intact the layer "dough").

I can see two good but different fixes for this issue:

A: The texture from other layers is not affected, only the current layer's pixels are moved with the UV.

I personally prefer this one, for being generally both more useful and clear.

or

B: The current behavior is generally kept: the pixels of all layers are moved, except they stay on their own layers, don't make a copy on the currently selected layer.

Potentially you could select multiple layers while in the Paint tab, to pick those affected in the UV tab? Currently, only one layer at a time can be selected.

Maybe having it work like A or B should be customizable via a Setting.
