Bug 55827 [Contributions] Need to remove refs to Platform.getDebugOption from JFace

	 * standard margins and spacing.

	 * The returned control's layout data must be an instance of 
	 * <code>GridData</code>. This method must not modify the parent's layout.

	 * 	//add controls to composite as necessary
	 * 	return composite;

	 * @param parent the parent composite to contain the dialog area
	 * @return the dialog area control
