Let's take a very simple example:

window := SystemWindow new.
window addMorph: (LabelMorph new contents: 'Hello World').
window layoutSubmorphs.
window openInWorld.

The window will be much larger than what is required to hold the LabelMorph.
Sending #layoutSubmorphs doesn't seem to affect the window size in this
case.
What can I do to tell the SystemWindow that I want its extent to be the
minimum required to display its submorphs.
Side note: I have spent hours digging through the source code trying to
figure it out on my own.
