NAME
       CGlue - connector glue

SYNOPSIS
       #include <Unidraw/cglue.h>

DESCRIPTION
       CGlue  defines  a  natural  size,  elasticity (its rate of stretching and shrinking relative to other CGlue), and deformation limits (total
       amount it can stretch and shrink) in both the horizontal and vertical dimensions.  CGlue can be interposed between two connected connectors
       to  augment  their connectivity semantics; it acts like two non-linear springs, one horizontal and one vertical, connecting the connectors'
       centers.

PUBLIC OPERATIONS
       CGlue(

	   float hnat = 0, float vnat = 0,
	   float hshr = 0, float hstr = 0,
	   float vshr = 0, float vstr = 0,
	   float hshrlim = 0, float hstrlim = 0,
	   float vshrlim = 0, float vstrlim = 0
       )

       CGlue(const Shape&)
	      Instantiate CGlue, providing the requisite parameters explicitly or inferring them from a Shape object.  If  a  shape  is  supplied,
	      then  the  CGlue	adopts	the shape's natural size, and it assigns the shape's stretchability and shrinkability values to its corre-
	      sponding CGlue elasticity members to obtain a proportionately equivalent elasticity.  It also assigns the shape's stretchability and
	      shrinkability values to its deformation limit members.  The parameters are described below:

	      hnat, vnat: horizontal and vertical natural sizes, screen units

	      hshr, vshr: horizontal and vertical shrinking rate, constant units

	      hstr, vstr: horizontal and vertical stretching rate, constant units

	      hshrlim, vshrlim: horizontal and vertical shrink limit, screen units

	      hstrlim, vstrlim: horizontal and vertical stretch limit, screen units

       CGlue* Copy()
	      Create a copy of this CGlue instance.

       void Rigid()
	      Set all elasticity and deformation limits equal to zero.

       void Interpose(const CGlue* glue)
	      Change this instance's attributes to reflect the series combination of this and glue.
