magic is compiled with the OpenGL
	graphics option and invoked with <B>magic -d OGL</B>. <P>
	
      Note that macros of the <B>wind3d</B> window are hard-coded,
	and cannot be changed with the <B>macro</B>, <B>gmacro</B>, or
	<B>imacro</B> commands.  There is no "<TT>:</TT>" macro for
	entering commands; to enter commands from the command-line,
	use the <A HREF=../tk_path_name.html> <I>tk_path_name</I></A>
	command.  The default Tk path name of the <B>wind3d</B> window
	is "<TT>.magic3d</TT>".
