Is this what you mean by "original layer"? If a layer stack has two 
layers, A and B, with B as the upper layer, and if a 
transform/rotate/etc tool is used on B, the "original layer" is layer B 
*before* the tranform, and the transformed layer is what B would look 
like if the transform were made using the current settings.

If I understand what you mean by "original layer", I don't need to see 
the original layer B. What I really do need to see is layer A, meaning 
I'd like the option to set the opacity of the transformed layer B to 50% 
so I can compare the transformed layer B to layer A.

Unfortunately right now lowering the opacity of layer B on which the 
transform is being done doesn't seem to allow to see layer A through the 
*transformed* layer B.
