    # Proxy for org.eclipse.swt.widgets.TabItem
    #
    # Functions differently from other widget proxies.
    #
    # Glimmer instantiates an SWT Composite alongside the SWT TabItem
    # and returns it for `#swt_widget` to allow adding widgets into it.
    #
    # In order to get the SWT TabItem object, one must call `#swt_tab_item`.
    #
    # Behinds the scenes, this creates a tab item widget proxy separately from a composite that
    # is set as the control of the tab item and `#swt_widget`.
    #
    # In order to retrieve the tab item widget proxy, one must call `#widget_proxy`
    #
    # Follows the Proxy Design Pattern
