	// Handle GUI_CONTROL_RADIO separately so that any radio group that has a single name
	// to share among all its members can be given special treatment:
	int group_radios = 0;           // The number of radio buttons in the current group.
	int group_radios_with_name = 0; // The number of the above that have a name.

	// The below uses <= so that it goes one beyond the limit.  This allows the final radio group
	// (if any) to be noticed in the case where the very last control in the window is a radio button.
	// This is because in such a case, there is no "terminating control" having the WS_GROUP style:
	for (u = 0; u <= mControlCount; ++u)
	{
		GuiControlType& control = *mControl[u]; // For performance and readability.

		// WS_GROUP is used to determine where one group ends and the next begins -- rather than using
		// seeing if the control's type is radio -- because in the future it may be possible for a radio
		// group to have other controls interspersed within it and yet still be a group for the purpose
		// of "auto radio button (only one selected at a time)" behavior:
		if (u == mControlCount || GetWindowLong(control.hwnd, GWL_STYLE) & WS_GROUP) // New group. Relies on short-circuit boolean order.
		{
			// If the prior group had more than one radio in it but only one had a name, that
			// name is shared among all radios (as of v1.0.20).  Otherwise:
			// 1) If it has zero radios and/or zero names: already fully handled by other logic.
			// 2) It has multiple names: the default values assigned in the loop are simply retained.
			// 3) It has exactly one radio in it and that radio has a name: same as above.
