I've added a bit more to this example view. There are now two swing
controls side by side. The grow and shrink buttons add to the preferred
size both vertically and horizontally. The SWT grow/shrink buttons work
on both swing controls at once.
There's some odd behavior with the new example that needs some
investigation. Not sure if it is a bug in the example, strange SWT
behavior, or a bug in albireo.
For example, growing both controls at once is not always as symmetrical
as I would have expected.
