Transparent stacks....

Not intending to take the thread off-topic, but:

What is the recommended way (if there is one) to have a resizable stack that 
also has a custom shape? For example if you wanted to have rounded corners.

I tried at first going down the "transparent stack" route with opaque 
objects on it to create the appearance of a windowshape. But that didn't 
work for the reasons already mentioned.

It would seem that the only way would be to have five or more stacks that 
all monitor/update their positions -- one each for the corners (with the 
windowshape) and one for the "central" region that is no-decorations.
