NAME
	  glColorMaterial - cause a material color to track the
	  current color


     C SPECIFICATION
	  void glColorMaterial(	GLenum face,
				GLenum mode )


     PARAMETERS
	  face	Specifies whether front, back, or both front and back
		material parameters should track the current color.
		Accepted values	are GL_FRONT, GL_BACK, and
		GL_FRONT_AND_BACK.  The	initial	value is
		GL_FRONT_AND_BACK.

	  mode	Specifies which	of several material parameters track
		the current color.  Accepted values are	GL_EMISSION,
		GL_AMBIENT, GL_DIFFUSE,	GL_SPECULAR, and
		GL_AMBIENT_AND_DIFFUSE.	 The initial value is
		GL_AMBIENT_AND_DIFFUSE.

     DESCRIPTION
	  glColorMaterial specifies which material parameters track
	  the current color.  When GL_COLOR_MATERIAL is	enabled, the
	  material parameter or	parameters specified by	mode, of the
	  material or materials	specified by face, track the current
	  color	at all times.

	  To enable and	disable	GL_COLOR_MATERIAL, call	glEnable and
	  glDisable with argument GL_COLOR_MATERIAL.
	  GL_COLOR_MATERIAL is initially disabled.

     NOTES
	  glColorMaterial makes	it possible to change a	subset of
	  material parameters for each vertex using only the glColor
	  command, without calling glMaterial.	If only	such a subset
	  of parameters	is to be specified for each vertex, calling
	  glColorMaterial is preferable	to calling glMaterial.

	  Call glColorMaterial before enabling GL_COLOR_MATERIAL.

	  Calling glDrawElements may leave the current color
	  indeterminate.  If glColorMaterial is	enabled	while the
	  current color	is indeterminate, the lighting material	state
	  specified by face and	mode is	also indeterminate.

	  If the GL version is 1.1 or greater, and GL_COLOR_MATERIAL
	  is enabled, evaluated	color values affect the	results	of the
	  lighting equation as if the current color were being
	  modified, but	no change is made to the tracking lighting
	  parameter of the current color.

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

	  GL_INVALID_OPERATION is generated if glColorMaterial is
	  executed between the execution of glBegin and	the
	  corresponding	execution of glEnd.

     ASSOCIATED	GETS
	  glIsEnabled with argument GL_COLOR_MATERIAL
	  glGet	with argument GL_COLOR_MATERIAL_PARAMETER
	  glGet	with argument GL_COLOR_MATERIAL_FACE
