Put bring up the halos on a morph, press the debug halo (gray wrench),
and inspect morph. Look at the fullBounds, now drag the morph around.

Try to inspect anything you don't understand - you might still not
understand how it works, but you'll know quite a bit about it.

For example, try to inspect (alt-i / cmd-i)-
World findDeeplyA: TextMorph

This lets you get examples for the different morph subclasses, and where
they're used. And if one isn't used, that's also information.

Have fun.
