SystemWindows are not the only way to group Morphs. A lot of the tools 
made by the original Squeak devs used PasteUpMorph to group Morphs or 
just bare Morphs and halos are the best way to interact with those.

I don't actually like how SystemWindows are the go to for grouping 
Morphs. They lose a lot of power in exchange for convenience. IIRC, they 
were originally introduced to make it easier to port the existing dev 
tools from the MVC GUI, not as the standard way to make tools.
