NAME
	  fglCullFace -	specify	whether	front- or back-facing facets
	  can be culled


     FORTRAN SPECIFICATION
	  SUBROUTINE fglCullFace( INTEGER*4 mode )


     PARAMETERS
	  mode	Specifies whether front- or back-facing	facets are
		candidates for culling.	 Symbolic constants GL_FRONT,
		GL_BACK, and GL_FRONT_AND_BACK are accepted.  The
		initial	value is GL_BACK.

     DESCRIPTION
	  fglCullFace specifies	whether	front- or back-facing facets
	  are culled (as specified by mode) when facet culling is
	  enabled. Facet culling is initially disabled.	 To enable and
	  disable facet	culling, call the fglEnable and	fglDisable
	  commands with	the argument GL_CULL_FACE.  Facets include
	  triangles, quadrilaterals, polygons, and rectangles.

	  fglFrontFace specifies which of the clockwise	and
	  counterclockwise facets are front-facing and back-facing.
	  See fglFrontFace.

     NOTES
	  If  mode is GL_FRONT_AND_BACK, no facets are drawn, but
	  other	primitives such	as points and lines are	drawn.

     ERRORS
	  GL_INVALID_ENUM is generated if mode is not an accepted
	  value.

	  GL_INVALID_OPERATION is generated if fglCullFace is executed
	  between the execution	of fglBegin and	the corresponding
	  execution of fglEnd.

     ASSOCIATED	GETS
	  fglIsEnabled with argument GL_CULL_FACE
	  fglGet with argument GL_CULL_FACE_MODE
