# 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`.
#
# Behind 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
