Tab one has a ScrollView that has struts and springs to maintain full screen
size. This scrollview has three UIViews that together fill up more than one
screen (thus the scrollview).
Tab 2 needs a full-screen background image that is a darkened version of the
current position and view of the scroillview in tab 1.
If I have tab 2 selected and rotate the device, I need tab 1 to reconfigure
its views so that I can grab a "snapshot" of the scrollview in tab 1.
As it is now, tab one will not resize itself until it is selected.
If I can't figure this out, I'll have to put a similar scrollview in tab 2
that is just a copy of the one in tab 1, but that is less than ideal.
