<B>cgD3D9GetOptimalOptions</B> returns the best set of compiler options for a
given profile. This is an expanded interface function because it needs to
know about the D3D device to determine the most optimal options.
</P>
<P>
The elements of the returned array are meant to be used as part of the
<B>args</B> parameter to <A HREF="cgCreateProgram.html">cgCreateProgram</A> or
<A HREF="cgCreateProgramFromFile.html">cgCreateProgramFromFile</A>.
</P>
<P>
The returned string does not need to be destroyed by the application.
However, the contents could change if the function is called again for the
same profile but a different D3D device.
