A lot of useless futzing with the layouting

I'm trying to get the sizechanges from the extenders propagated up to the popup, to no avail.
Seems like I should just put this aside, wait for Qt 4.5 and see if that changes anything.

The surgery needed to get QGraphicsLayout to properly resize when one the contents of a cell changes size looks so icky, and it's so frustrating that I'm close to just giving up for Qt 4.4 and declare it broken beyond reasonable to fix.

The combination of dynamic layout (emailmessage) inside a dynamic layout (lionmail's MailExtender) inside an Extender inside a popup seems too much for either me, Qt, or -- quite likely -- both.

I've not tried 4.5 yet, but I have high hopes for it. (If that doesn't relieve us poor Plasma hackers, I'll probably just jump off a cliff, orequivalent.)
