[Cuis] Cuis on Raspberry Pi

[Casey Ransberger]

Well, we removed that. What that is, is when you move or resize a window,
in Squeak (when it's enabled, probably still default) will show you only
the outline of the window, a wireframe so to speak, which doesn't bother
rendering the window until you drop it somewhere.

Cuis is fast enough that we really don't need that stuff anymore on most
hardware. The Pi presents some new challenges. Personally I think we can
nail down what's slowing us and just fix it, but it may actually be worth
putting that behavior back in for folks running on pocket calculators.
(Mind you, I'm making a TRON reference here and not insulting the Pi, which
I'm really quite a fan of.)

Juan can lambast me to the extent that I've explained this situation
incorrectly. IIRC correctly (and I don't trust that I do) we dropped this
behavior in either Cuis 3.0 or 4.0. An industrious programmer might bring
it back in as an external package.

I think it's fairly certain that we'd like to be the ideal Smalltalk to run
on small/low-end devices like the Pi, so I do think this merits discussion.
