2.11 vs 2.12 - change in behavior regarding bg colors

[Doug Lerner]

I found the cause of my bg color problem.

In 2.1.1, if you set a stack's bg color that is what is shown in the IDE and
also in the standalone app.

But in 2.1.2 setting a stack's bg color only shows up in the IDE. You have
to set the *card's* bg color in order for it to also show up in the
standalone app.

I think this should be considered a 2.1.2 bug - either in the IDE or in the
created standalone app. At the minimum they should look the same.
