I20140115-1300, did not happen in 4.3.1

A part is not resized/layouted any more if it was previously shown in another perspective with a different size.

- new workspace, close Welcome
- switch to "Javadoc" view, thereby hiding the "Problems" view
- switch to "Plug-in Development" perspective
- reduce the height of the "Problems" view, so that only two rows stay visible
- switch back to the "Java" perspective
- click the "Problems" view tab

Broken since 4.4 M1.

This is easy to reproduce, now I wonder why there's not a bunch of DUPS...

This is the result of our playing around with the widget hierarchy using 'setParent' in order to support shared elements. It turns out that the CTF does correctly set the size of the Composite the CTabItem owns but (since it didn't actually change size) it doesn't lay out its children.

Committed:

This specifically causes the CTabItem to lay out its children. Note that it's only the *item* that is getting a layout so we're not re-introducing the performance issue...
