**		GM_LAYOUT			V40 Lays out self and then lays out the children.
**		GM_DOMAIN			V40 For all which's Top=Height=0,
**						    MINIMUM==NOMINAL Calculated size of all children but

** General Header File Information
***************************************************************************************************
**
** All class, method, value, macro and structure definitions follow these rules:
**
** Name				Meaning
**
** RGrpM_<method>		Method.
** RGrpP_<method>		Methods parameter structure.
** RGrpV_<method>_<x>		Special method value.
** RGrpA_<attrib>		Attribute.
** RGrpV_<attrib>_<x>		Special attribute value.
**
** All definitions are followed by a comment containing the version
** which introduced that definition.
** Attribute definitions are followed by a comment
** consisting of the three possible letters I, S and G.
** I: it's possible to specify this attribute at object creation (init) time.
** S: it's possible to change this attribute with SetAttrs().
** G: it's possible to get this attribute with GetAttr().
**
** The BOOPSI relgroup.gadget library uses the following structure as its base for the
** library data.  This allows developers to obtain the class pointer for
** performing object-less inquiries (As specified in the v42 classes.h/i).
**	struct ClassLibrary
**	{
**		struct Library	 cl_Lib;	/* Embedded library */
**		UWORD		 cl_Pad;	/* Align the structure */
**		Class		*cl_Class;	/* Class pointer */
**		/* Private data, has changed, is changing and will continue to change. */
**	};
