[Cuis-dev] Morph render leftovers when dragging the mouse

[Nicolás Papagna Maldonado]

Thanks, Juan and Ken!

@Juan Vuletich <juan at jvuletich.org> I defined #submorphsMightProtrude to
answer true and it worked like a charm.

@KenD <ken.dickey at whidbey.com> I (believe) I did that when trying to fix
the bug, the challenge is how to shrink/wrap the parent morph whenever one
of the submorphs changes. To make it work I took a look at the "morph
lifecycle" and noticed that layoutSubmorphs is called before a morph is
drawn. I redefined layoutSubmorphs in the parent and after calling super I
compute the parent extent based on the submorphs to shrink/wrap. Its fine
working so far, but I bet there will be unhandled edge cases.

Cheers,
Nico PM
