When locking a material, the preview icon would get greyed-out (as would the rest of the properties in the row). This issue is that this defeats the purpose of an accurate preview of the material. Artists want to know what the material _actually_ looks like. This moves the icon into a separate row and property so that it doesn't get disabled.
