Glue , and related subclasses - open space between interactors

#include <InterViews/glue.h>

A glue object is an interactor that is used to define variable-size space between interactors in boxes. The HGlue subclass is for space in a horizontal box; VGlue for space in a vertical box. Along its minor axis (vertical for HGlue, horizontal for VGlue), glue has a natural size of zero and infinite stretchability.

HGlue(int natural = 0, int stretch = hfil)
VGlue(int natural = 0, int stretch = vfil)

Construct glue of a minimum size. The glue can be stretched arbitrarily, but cannot shrink.

HGlue(int natural, int shrink, int stretch)
VGlue(int natural, int shrink, int stretch)

Construct glue with a given natural size, shrinkability, and stretchability. If shrink is larger than natural the glue potentially can have ``negative size'', meaning interactors will overlap in a box.
