NAME
       Vertices - abstract base class for graphics defined by a set of coordinate pairs

SYNOPSIS
       #include <Unidraw/Graphic/verts.h>

DESCRIPTION
       Vertices is an abstract base class for graphics such as polygons and splines whose geometry is specified by a set of coordinate pairs.  The
       Vertices class supports vertex-related operations common to all such graphical objects and also supports extent caching.

PUBLIC OPERATIONS
       virtual ~Vertices()
	      The destructor deallocates the list of coordinate pairs stored in the graphic.

       virtual int GetOriginal(const Coord*& x, const Coord*& y)
	      Return pointers to the arrays of Coords stored internally that define the graphic's vertices.  GetOriginal's return  value  reflects
	      the size of the arrays.

       virtual boolean operator == (Vertices&)
       virtual boolean operator != (Vertices&)
	      Compare this to the given Vertices instance and return whether they (do not) store identical sets of vertices.

PROTECTED OPERATIONS
       Vertices(Graphic* = nil)
       Vertices(Coord* x, Coord* y, int count, Graphic* = nil)
	      The  constructors are protected to disallow instantiation of the abstract class.	Subclasses can pass a set of vertices to copy into
	      internal storage and an optional graphic from which to obtain an initial set of graphics state.  Vertices  itself  stores  no  addi-
	      tional graphics state over that in the Graphic base class.

       void s_getExtent(
	   float&, float&, float&, float&, float&, Graphic*
       )

       void f_getExtent(
	   float&, float&, float&, float&, float&, Graphic*
       )
	      Helper  functions  that return extent information based on the bounding box that the vertices define.  s_getExtent returns an extent
	      that accounts for the width of a brush, as would be necessary if the vertices defined a stroked path, while f_getExtent assumes that
	      the  vertices  define the graphic's extremities, as would be the case if the vertices defined a filled path.  These operations cache
	      the extent they compute initially.
