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 corresponding 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
