Bug 207188 [Dialogs] org.eclipse.jface.dialogs.Dialog.shortenText calls GC.textExtent too often
bundles/org.eclipse.jface/src/org/eclipse/jface/dialogs/Dialog.java
}
	
	/**
	 * Returns a boolean indicating whether the dialog should be
	 * considered resizable when the shell style is initially
	 * set.  
	 * 
	 * This method is used to ensure that all style 
	 * bits appropriate for resizable dialogs are added to the 
	 * shell style.  Individual dialogs may always set the shell 
	 * style to ensure that a dialog is resizable, but using this
	 * method ensures that resizable dialogs will be created with
	 * the same set of style bits.
	 * 
	 * Style bits will never be removed based on the return value 
	 * of this method.  For example, if a dialog returns 
	 * <code>false</code>, but also sets a style bit for a 
	 * SWT.RESIZE border, the style bit will be honored.
	 * 
	 * @return a boolean indicating whether the dialog is 
	 * resizable and should have the default style bits for
	 * resizable dialogs
	 * 
	 * @since 3.4
