* handle brightmaps in the main shader instead of keeping separate instances around. * added detail and glow layers from Raze. * fixed material setup which could not guarantee that everything was initialized correctly. * for warped textures, warp all layers. With this brightmaps finally work on warped textures. Note: Vulkan reports a "device lost" error with this which still needs to be investigated.
