DDS cube map sides.

<p>Note that if you work in right-handed coordinate system (like OpenGL, see <a  href="http://opengl.org/registry/specs/ARB/texture_cube_map.txt">http://opengl.org/registry/specs/ARB/texture_cube_map.txt</a>) then you should swap the meaning of positive/negative y faces. That's because cube map sides are named and written in DDS file in a way natural for DirectX, and DirectX has left-handed coordinate system, which means that one axis seems reverted when you want OpenGL right-handed coord system. See [<a  href="http://castle-engine.sourceforge.net/x3d_implementation_status.php#section_dds">http://castle-engine.sourceforge.net/x3d_implementation_status.php#section_dds</a>] for more.</p>
