NAME
	  DtShapeGetTextureVertex - Get	a texture vertex for the given
	  shape	and texture vertex index.


     SYNOPSIS
	  #include <Dt.h>


	  int  DtShapeGetTextureVertex(	int shapeID, int index,	DtVec2f	*vertex	)


     DESCRIPTION
	  DtShapeGetTextureVertex() returns a texture vertex for the
	  shape	indicated by the given shapeID and index. The texture
	  vertex is returned via the pointer to	the vertex parameter.
	  C programmers	can access the components of the texture
	  vertex vector	as though it were a simple structure as
	  follows:

		    typedef struct DtVec2f { float vec[2];};

		    DtVec2f tVert;
		    u =	tVert.vec[0];
		    v =	tVert.vec[1];


     DIAGNOSTICS
	  DtShapeGetTextureVertex() returns one	on success and zero on
	  failure.
