NAME
	  glEnableClientState, glDisableClientState - enable or
	  disable client-side capability


     C SPECIFICATION
	  void glEnableClientState( GLenum cap )


     PARAMETERS
	  cap  Specifies the capability	to enable.  Symbolic constants
	       GL_COLOR_ARRAY, GL_EDGE_FLAG_ARRAY, GL_INDEX_ARRAY,
	       GL_NORMAL_ARRAY,	GL_TEXTURE_COORD_ARRAY,	and
	       GL_VERTEX_ARRAY are accepted.

     C SPECIFICATION
	  void glDisableClientState( GLenum cap	)


     PARAMETERS
	  cap  Specifies the capability	to disable.

     DESCRIPTION
	  glEnableClientState and glDisableClientState enable or
	  disable individual client-side capabilities. By default, all
	  client-side capabilities are disabled.  Both
	  glEnableClientState and glDisableClientState take a single
	  argument, cap, which can assume one of the following values:

	  GL_COLOR_ARRAY	   If enabled, the color array is
				   enabled for writing and used	during
				   rendering when glDrawArrays or
				   glDrawElement is called. See
				   glColorPointer.

	  GL_EDGE_FLAG_ARRAY	   If enabled, the edge	flag array is
				   enabled for writing and used	during
				   rendering when glDrawArrays or
				   glDrawElements is called. See
				   glEdgeFlagPointer.

	  GL_INDEX_ARRAY	   If enabled, the index array is
				   enabled for writing and used	during
				   rendering when glDrawArrays or
				   glDrawElements is called. See
				   glIndexPointer.

	  GL_NORMAL_ARRAY	   If enabled, the normal array	is
				   enabled for writing and used	during
				   rendering when glDrawArrays or
				   glDrawElements is called. See
				   glNormalPointer.

	  GL_TEXTURE_COORD_ARRAY   If enabled, the texture coordinate
				   array is enabled for	writing	and
				   used	for rendering when
				   glDrawArrays	or glDrawElements is
				   called. See glTexCoordPointer.

	  GL_VERTEX_ARRAY	   If enabled, the vertex array	is
				   enabled for writing and used	during
				   rendering when glDrawArrays or
				   glDrawElements is called. See
				   glVertexPointer.

     NOTES
	  glEnableClientState is available only	if the GL version is
	  1.1 or greater.

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

	  glEnableClientState is not allowed between the execution of
	  glBegin and the corresponding	glEnd, but an error may	or may
	  not be generated. If no error	is generated, the behavior is
	  undefined.
