NAME
	  glPushName, glPopName	- push and pop the name	stack


     C SPECIFICATION
	  void glPushName( GLuint name )


     PARAMETERS
	  name	Specifies a name that will be pushed onto the name
		stack.

     C SPECIFICATION
	  void glPopName( void )


     DESCRIPTION
	  The name stack is used during	selection mode to allow	sets
	  of rendering commands	to be uniquely identified.  It
	  consists of an ordered set of	unsigned integers and is
	  initially empty.

	  glPushName causes name to be pushed onto the name stack.
	  glPopName pops one name off the top of the stack.

	  The maximum name stack depth is implementation-dependent;
	  call GL_MAX_NAME_STACK_DEPTH to find out the value for a
	  particular implementation. It	is an error to push a name
	  onto a full stack, or	to pop a name off an empty stack.  It
	  is also an error to manipulate the name stack	between	the
	  execution of glBegin and the corresponding execution of
	  glEnd.  In any of these cases, the error flag	is set and no
	  other	change is made to GL state.

	  The name stack is always empty while the render mode is not
	  GL_SELECT.  Calls to glPushName or glPopName while the
	  render mode is not GL_SELECT are ignored.

     ERRORS
	  GL_STACK_OVERFLOW is generated if glPushName is called while
	  the name stack is full.

	  GL_STACK_UNDERFLOW is	generated if glPopName is called while
	  the name stack is empty.

	  GL_INVALID_OPERATION is generated if glPushName or glPopName
	  is executed between a	call to	glBegin	and the	corresponding
	  call to glEnd.
