3	# COMPONENT: SidebarFrame - pop-out controls for visualization widgets
4	#
5	# The sidebar provides a way to put a thin strip of controls along the
6	# side of a visualization widget, with tabs that cause control panels
7	# to pop out. The SidebarFrame has an empty frame (component "frame")
8	# on the left and a sidebar that pops out on the right.
