	// Floaters controlled by the toolbar behave a bit differently from others.
	// Namely they have 3-4 states as defined in the design wiki page here:
	//   https://wiki.lindenlab.com/wiki/FUI_Button_states
	//
	// The basic idea is this:
	// * If the target floater is minimized, this button press will un-minimize it.
	// * Else if the target floater is closed open it.
	// * Else if the target floater does not have focus, give it focus.
	//       * Also, if it is not on top, bring it forward when focus is given.
	// * Else the target floater is open, close it.
