The atlas tag is being used internally right now, but the next version of UIBuilder we ship will include support for it. We are working on a texture optimization tool that will take all the little texture pieces and put them into large texture atlases automatically. Atlas="none" means don't do that. You can also explicitly specify an atlas by using any string, I believe NCS2 does this by tagging stuff as Atlas="NCS2"
