Bug 214754 ControlExample's "Select Listeners" has sizing problems
examples/org.eclipse.swt.examples/src/org/eclipse/swt/examples/controlexample/Tab.java
* column contains "Control" group.  The "Control" group
 * contains controls that allow the user to interact with
 * the example control.  The "Control" group typically
 * contains a "Style", "Other" and "Size" group.  Subclasses
 * can override these defaults to augment a group or stop
 * a group from being created.
